MOTOROLA ANALOG IC DEVICE DATA
GENERAL DESCRIPTION
The TDA 1085C triggers a triac accordingly to the speed regulation requirements. Motor speed is digitally sensed by a tachogenerator and then converted into an analog voltage.
The speed set is externally fixed and is applied to the internal linear regulation input after having been submitted to programmable acceleration ramps. The overall result consists in a full motor speed
range with two acceleration ramps which allow efficient washing machine control (Distribute function).
Additionally, the TDA 1085C protects the whole system against AC line stop or variations, overcurrent in the motor and tachogenerator failure.
INPUT/OUTPUT FUNCTIONS
(Refer to Figures 1 and 8)
Voltage Regulator – (Pins 9 and 10) This is a parallel type regulator
able to sink a large amount of current and offering good characteristics. Current flow is provided from AC line by external dropping resistors R1, R2, and rectifier: This half wave current is used to feed a smoothering capacitor, the voltage of which is checked by the IC.
When VCC is reached, the excess of current is derived by another dropping resistor R10 and by Pin 10. These three resistors must be determined in order:
To let 1.0 mA flow through Pin 10 when AC line is minimum and V
CC
consumption is maximum (fast ramps and pulses present).
To let V
10
reach 3.0 V when AC line provides maximum current and
VCC consumption is minimum (no ramps and no pulses).
All along the main line cycle, the Pin 10 dynamic range must not be
exceeded unless loss of regulation. An AC line supply failure would cause shut down. The double capacitive filter built with R1 and R2 gives an efficient
VCC smoothing and helps to remove noise from set speeds. Speed Sensing – (Pins 4, 11, 12) The IC is compatible with an
external analog speed sensing: its output must be applied to Pin 4, and Pin 12 connected to Pin 8.
In most of the applications it is more convenient to use a digital speed sensing with an unexpensive tachogenerator which doesnt need any tuning. During e very positive cycle at Pin 12, the c apacitor C
Pin 11
is charged to almost VCC and during this time, Pin 4 delivers a current which is 10 times the one charging C
Pin 11
. The current source gain is called G and is tightly
specified, but nevertheless requires an adjustment on R
Pin 4
. The
current into this resistor is proportional to C
Pin 11
and to the motor
speed; being filtered by a capacitor, V
Pin 4
becomes smothered
and represents the “true actual motor speed”. To maintain linearity into the high speed range, it is important to verify
that C
Pin 11
is fully charged: the internal source on Pin 11 has 100K
impedance. Nevertheless C
Pin 11
has to be as high as possible as it has a large influence on FV/C temperature factor. A 470 K resistor between Pins 11 and 9 reduces leakage currents and temperature factor as well, down to neglectable effects.
Pin 12 also has a monitoring function: when its voltage is above
5.0 V, the trigger pulses are inhibited and the IC is reset. It also senses the tachogenerator continuity, and in case of any circuit aperture, it inhibits pulse, avoiding the motor to run out of control. In the TDA 1085C, Pin 12 is negatively clamped by an internal diode which removes the necessity of the external one used in the former circuit.
Ramp Generator – (Pins 5, 6, 7) The true Set Speed value taken in consideration by the regulation is the output of the ramp generator (Pin 7). With a given value of speed set input (Pin 5), the ramp generator charges an external capacitor C
Pin 7
up to the moment
V
Pin 5
(set speed) equals V
Pin 4
(true speed), see Figure 2. The IC has an internal charging current source of 1.2mA and delivers it from 0 to 12 V at Pin 7. It is the high acceleration ramp (5.0 s typical) which allows rapid motor speed changes without excessive strains on the mechanics. In addition, the TDA 1085C offers the possibility to break this high acceleration with the introduction of a low acceleration ramp (called Distribution) by reducing the Pin 7 source current down to
5.0 µA under Pin 6 full control, as shown by following conditions:
Presence of high acceleration ramp V
Pin 5
> V
Pin 4
Distribution occurs in the V
Pin 4
range (true motor speed) defined
by V
Pin 6
x V
Pin 4
x 2.0 V
Pin 6
For two fixed values of V
Pin 5
and V
Pin 6
, the motor speed will have
high acceleration, excluding the time for V
Pin 4
to go from V
Pin 6
to two times this value, high acceleration again, up to the moment the motor has reached the set speed value, at which it will stay, see Figure 3.
Should a reset happen (whatever the cause would be), the above mentioned successive ramps will be fully reprocessed from 0 to the maximum speed. If V
Pin 6
= 0, only t he high acceleration ramp
occurs. To get a real zero speed position, Pin 5 has been designed in such a
way that its voltage from 0 to 80 mV is interpreted as a true zero. As a consequence, when changing the speed set position, the designer must be sure that any transient zero would not occur: if any, the entire circuit will be reset.
As the voltages applied by Pins 5 and 6 are derived from the internal voltage regulator supply and Pin 4 voltage is also derived from the same source, motor speed (which is determined by the ratios between above mentioned voltages) is totally independent from V
CC
variations and temperature factor. Control Amplifier – (Pin 16) It amplifies the difference between true
speed (Pin 4) and set speed (Pin 5), through the ramp generator. Its output available at Pin 16 is a double sense current source with a maximum capability of ± 100 µA and a specified transconductance (340 µA/V typical). Pin 16 drives directly the trigger pulse generator, and must be loaded by an electrical network which compensates the mechanical characteristics of the motor and its load, in order to provide stability in any condition and shortest transient response; see Figure 4.
This network must be adjusted experimentally. In case of a periodic torque variations, Pin 16 directly provides the
phase angle oscillations.

Trigger Pulse Generator – (Pins 1, 2, 5, 13, 14, 15)
This circuit performs four functions:
The conversion of the control amplifier DC output level to a
proportional firing angle at every main line half cycle.
The calibration of pulse duration.
The repetition of the pulse if the triac fails to latch on if the current
has been interrupted by brush bounce.
The delay of firing pulse until the current crosses zero at wide firing
angles and inductive loads.
R
Pin 15
programs the Pin 14 discharging current. Saw tooth signal is then fully determined by R15 and C14 (usually 47 nF). Firing pulse duration and repetition period are in inverse ratio to the saw tooth slope.
Pin 13 is the pulse output and an external limiting resistor is mandatory. Maximum current capability is 200 mA.
Current Limiter – (Pin 3) Safe operation of the motor and triac under all conditions is ensured by limiting the peak current. The motor current develops an alternative voltage in the shunt resistor (0.05 in Figure 4). The negative half waves are transferred to Pin 3 which is positively preset at a voltage determined by resistors R3 and R4. As motor current increases, the dynamical voltage range of Pin 3 increases and when Pin 3 becomes slightly negative in respect to Pin 8, a current starts to circulate in it. This current, amplified typically 180 times, is then used to discharge Pin 7 capacitor and, as a result, reduces firing angle down to a value where an equilibrium is reached. The choice of resistors R3, R4 and shunt determines the magnitude of the discharge current signals on C
Pin 7
.
Notice that the current limiter acts only on peak triac current.
APPLICATION NOTES
(Refer to Figure 4)
Printed Circuit Layout Rules
In the common applications, where TDA 1085C is used, there is on the same board, presence of high voltage, high currents as well as low voltage signals where millivolts count. It is of first magnitude importance to separate them from each other and to respect the following rules:
Capacitor decoupling pins, which are the inputs of the same
comparator, must be physically close to the IC, close to each other and grounded in the same point.
Ground connection for tachogenerator must be directly connected
to Pin 8 and should ground only the tacho. In effect, the latter is a first magnitude noise generator due to its proximity to the motor which induces high dφ/dt signals.
The ground pattern must be in the “star style” in order to fully
eliminate power currents flowing in the ground network devoted to capacitors decoupling sensitive Pins: 4, 5, 7, 11, 12, 14, 16.
As an example, Figure 5 presents a PC board pattern which concerns the group of sensitive Pins and their associated capacitors into which the a.m. rules have been implemented. Notice the full separation of “Signal World” from “Power”, one by line AB and their communication by a unique strip.
These rules will lead to much satisfactory volume production in the sense that speed adjustment w ill stay valid in the entire speed range.
Power Supply
As dropping resistor dissipates noticeable power, it is necessary to reduce the ICC needs down to a minimum. Triggering pulses, if a certain number of repetitions are kept in reserve to cope with motor brush wearing at the end of its life, are the largest ICC user. Classical worst case configuration has to be considered to select dropping resistor. In addition, the parallel regulator must be always into its dynamic range, i.e., I
Pin 10
over 1.0 mA and V
Pin 10
over 3.0 V in any
extreme configuration. The double filtering cell is mandatory.
Tachogenerator Circuit
The tacho signal voltage is proportional to the motor speed. Stablility considerations, in addition, require an RC filter, the pole of which must be looked at. The combination of both elements yield a constant amplitude signal on Pin 12 in most of the speed range. It is recommended to verify this maximum amplitude to be within 1.0 V
peak in order to have the largest signal/noise ratio without resetting the integrated circuit (which occurs if V
Pin 12
reaches 5.5 V). It must be also verified that the Pin 12 signal is approximately balanced between “high” (over 300 mV) and “low”. An 8–poles tacho is a minimum for low speed stability and a 16–poles is even better.
The RC pole of the tacho circuit should be chosen within 30 Hz in order to be as far as possible from the 150 Hz which corresponds to the AC line 3rd harmonic generated by the motor during starting procedure. In addition, a high value resistor coming from V
CC
introduces a positive offset at Pin 12, removes noise to be interpreted as a tacho signal. This offset should be designed in order to let Pin 12 reach at least – 200 mV (negative voltage) at the lowest motor speed. We remember the necessity of an individual tacho ground connection.
Frequency to Voltage Converter – F V/C
C
Pin
11 has a recommended value of 820 pF for 8–poles tachos and
maximum motor rpm of 15000, and R
Pin
11 must be always 470 K.
R
Pin 4
should be choosen to deliver within 12 V at maximum motor speed in order to maximize signal/noise ratio. As the FV/C ratio as well as the C
Pin 11
value are dispersed, R
Pin 4
must be adjustable and should be made of a fixed resistor in serice with a trimmer representing 25% of the total. Adjustment would become easier.
Once adjusted, for instance at maximum motor speed, the FV/C presents a residual non linearity; the conversion factor (mV per RPM) increases by within 7.7% as speed draws to zero. The guaranteed dispersion of the latter being very narrow, a maximum 1% speed error is guaranteed if during Pin 5 network design the small set values are modified, once forever, according this increase.

Speed Set – (Pin 5) Upon designer choice, a set of external resistors apply a series of various voltages corresponding to the various motor speeds. When switching external resistors, verify that no voltage below 80 mV is ever applied to Pin 5. If so, a full circuit reset will occur.

Ramps Generator – (Pin 6) If only a high acceleration ramp is
needed, connect Pin 6 to ground. When a Distribute ramp should occur, preset a voltage on Pin 6
which corresponds to the motor speed starting ramp point. Distribution (or low ramp) will continue up to the moment the motor speed would have reached twice the starting value.
The ratio of two is imposed by the IC. Nevertheless, it could be externally changed downwards (Figure 6) or upwards (Figure 7).
The distribution ramp can be shortened by an external resistor from VCC charging C
Pin 7
, adding its current to the internal 5.0 µA
generator.
Power Circuits
Triac Triggering pulse amplitude must be determined by Pin 13 resistor according to the needs in Quadrant IV . Trigger pulse duration can be disturbed by noise signals generated by the triac itself, which interfere within Pins 14 and 16, precisely those which determine it. While easily visible, this effect is harmless.
The triac must be protected from high AC line dV/dt during external disturbances by 100 nF x 100 network.
Shunt resistor must be as non–inductive as possible. It can be made locally by using constantan alloy wire.
When the load is a DC fed universal motor through a rectifier bridge, the triac must be protected from commutating dV/dt by a 1.0 to
2.0 mH coil in series with MT2. Synchronization functions are performed by resistors sensing AC
line and triac conduction. 820 k values are normal but could be reduced down to 330 k in order to detect the “zeros” with accuracy and to reduce the residual DC line component below 20 mA.
Current Limitation
The current limiter starts to discharge Pin 7 capacitor (reference speed) as the motor current reaches the designed threshold level. The loop gain is determined by the resistor connecting Pin 3 to the series shunt. Experience has shown that its optimal value for a 10 Arms limitation is within 2.0 k. Pin 3 input has a sensitivity in current which is limited to reasonable values and should not react to spikes.
If not used, Pin 3 must be connected to a maximum positive voltage of 5.0 V rather than be left open.
Loop Stability
The Pin 16 network is predominant and must be adjusted experimentally during module development. The values indicated in Figure 4 are typical for washing machine applications but accept large modifications from one model to another. R16 (the sole restriction) should not go below 33 k, otherwise slew rate limitation will cause large transient errors for load steps.
