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.

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.

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

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

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.

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.

VCM driver

The VCM driver is a linear, class AB, H-bridge type power driver with all power devices internal to the chip. In addition to the power stage a sense resistor enables VCM current to be measured and brought out to a separate ADC via the V
pin. The reference voltage for the V

). These PWM signals are filtered by an internal 3rd-order low-pass filter (Butterworth filter). The bandwidth of this low-pass filter is nominally 40 kHz (less than 2 degrees lag at 500 Hz), but the real pole may be adjustable by an external capacitor. The analog output of the filter depends on the duty factor of the PWM signal and not on the logic level.

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. The tC timing is set by the following equation:

A negative going pulse width of 5 µs on either the +5 or +12 V rail will provide a full output pulse. If another 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).

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.
