GENERAL DESCRIPTION

The TDA5147K is an ASIC combination chip that includes
the following functions; spindle motor drive, voice coil
motor drive, retract, and power-on. The circuit is contained
in a 52-pin PLCC package.

The TDA5147K (see Fig.1) is controlled by a custom
digital ASIC. The custom ASIC provides the necessary
commutation sequences for the spindle drivers via the
SCNTL1, SCNTL2 and SCNTL3 inputs. Spindle speed is
monitored by comparator outputs SENU, SENV and
SENWIS. Motor speed control is accomplished by a PWM
signal (input at the SIPWM pin).

Control of the VCM circuits is via the V
input signals. These two inputs provide control of the coil
current. The V

output signal can be used to monitor

ISENSE2

the voice coil current.

spindle motor drive combination chip

FUNCTIONAL DESCRIPTION
Spindle drivers

The spindle section contains both the low and high side
drivers (configured as H bridges) for a three-phase DC
brushless motor. Back EMF (BEMF) sensing of the
commutation rate needs to be output to an external digital
ASIC circuit. This digital circuit also provides the input
commutation control. Consequently, all speed control,
start-up routine and commutation control will be generated
by the digital circuit.

The SIPWM signal from the digital circuit is used to control
the spindle current. This PWM signal is internally filtered.
The output of this filter is duty factor dependent only. The
filter characteristics is that of a 1-pole low-pass filter, with
the pole location being controlled by the external capacitor
connected to pin SPWMFLT.

Dynamic braking is possible only during non power-down
situations and must be initiated by the digital circuit.

SMODE1

TDA5147K

to obtain high start-up torque. The purpose of the PWM
mode is to drive the low drivers into saturation (saturation
reduces the power dissipation in the TDA5147K during
start-up).

When the spindle current reaches the programmed set
current (SIPWM) value, a one-shot is fired. The output of
the one-shot remains high for the programmed off-time

) set by the capacitor/resistor network at the SPWMTC

(t

off

pin. The one-shot is not retriggerable for approximately
10% of the off-time, this gives a minimum of (10% t
time-on. During the off-time, the lower spindle output
drivers are switched off. The on-time of the drivers is not
fixed but is determined by the charging time of the coil
current to reach the program set current.

The turn-off time is calculated by the equation:
t

=R×C

Where R = 68 kΩ and C = 220 pF, t

A 3-state level mode line (SMODE1) has been included to
allow for;

2. PWM control during start-up (0.5V

3. Linear control (0 V).

S

ENSING MODE

The induction sensing mode is used for two purposes.
Firstly one of the BEMF sensor outputs (SENWIS) will be
shared with the voltage comparator that is used for the
induction sensing function. Prior to start-up each phase
can be excited for a short period of time. The current from
each coil can be monitored via the multiplexed output
(SENWIS). By comparing the rise times of each phase the
rotor position can be determined.

Secondly, in situations where the spindle motor requires
more current to spin-up, this mode is used with the
exception that the output SENWIS is ignored. Since, in the
induction sense mode, the output drivers are operated in
saturation mode, the motor current is limited only by the
power supply. This condition of induction sense mode can
be used to overcome the head friction and must be used
only when needed.

The linear mode is used when the motor is near to its

intended speed. It can also be used at start-up, but higher
power dissipation will occur. In the linear mode the linear
drivers are controlled by a sensing amplifier. A Miller
network is used to obtain soft switching on the lower
drivers. This prevents large voltage spikes on the motor
coils when the lower drivers are switching. The high drivers
are switched into the linear (resistive) region.

The transconductance gain of the low driver current to filter
voltage can be calculated as follows:

The duty factor is arranged so that at 100%, the voltage SPWMFLT = 1.74 V and at a 5% duty factor SPWMFLT = 0 V.
This is to ensure that at 0% duty factor the current will be zero (allowances for circuit tolerances).

The input decoder is driven by three lines which define the windings to be energized. The input decoder must then
translate these lines to six lines to drive the six output drivers. The truth table is given in Table 1.

the real pole may be adjustable by an external capacitor.

Power-on reset

The power-on reset circuit monitors the voltage levels of
both the +5 V and the +12 V supply voltages as shown
in Fig.6. The

POR (active LOW) logic line is set HIGH
following a supply voltage rise above a specified voltage
threshold plus a hysteresis, and delayed by a time, tC that

is controlled by an external capacitor. This

POR signal
should remain HIGH until either the +5 or +12 V supplies
drop below the voltage threshold, at which point the
line should be asserted LOW.

A negative going pulse width of 5 µs on either the

trigger pulse occurs before the output is completed a new
output pulse will be originated. This implies the power-on
reset circuit is a retriggerable one-shot with a maximum
trigger pulse of 5 µs (see Fig.7).

12 V Voice Coil Motor (VCM) driver and

TDA5147K

spindle motor drive combination chip

During a power-down situation the power-on reset circuit
must not only generate aPOR output signal, but must also
activate the VCM retract circuitry. In doing so, the VCM
driver draws power from the BEMF of the SDRVU output
during spin-down, and uses this power to bias the VCM
against one of the hard stops of the actuator. This prevents
the heads from landing on data zones. This BEMF supply
is isolated from the supply voltage for the drive, and is
half-wave rectified. An external retract capacitor is used to
provide the supply voltage for the retract circuit.

It should be noted that in both power-down retract and
command retract situations, the voltage across the VCM is
nominally limited to 1.2 V (to limit the velocity of the
actuator). Additional information is given in Fig.6.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

Reflow soldering

Reflow soldering techniques are suitable for all PLCC
packages.

The choice of heating method may be influenced by larger
PLCC packages (44 leads, or more). If infrared or vapour
phase heating is used and the large packages are not
absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our

Reference Handbook”

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

(order code 9398 652 90011).

Wave soldering

Wave soldering techniques can be used for all PLCC
packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream corners.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Repairing soldered joints

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
