4-Channel Motor driver
for Portable CD Player
Function Description
1. PWM switching regulated power supply drive
This circuit detects the maximum output level of four channels drivers and then generates PWM
signal accordingly. It uses a PNP transistor, a Schottky diode and a capacitor as external components.
2. Empty detector unit
3. Reset circuit
If the output voltage of the DC/DC converter is over than 90% of rating value, RESET terminal
varies from “L” to “H”, AMUTE terminal changes from “H” to “L” and Hysteresis is typically
50mV.

.
4. Charging circuit
The power supply for the charging unit is applied to the CHGVCC terminal. It is independent of any
other circuits. Charging current is set by the resistance between RCHG terminal and GND. A
constant charging current flows through SEL terminal.
5. Mute function
The BRAKE pin is low during normal operation (high to set CH1 mute on and enters a brake
mode).
• The MUTE2 pin is low during normal operation (high to set CH2 mute on).
• The MUTE34 pin is high during normal operation (low to set CH3,4 mute on).
6. VREF drop mute
Normally when the voltage of VREF terminal is above 1.0V, the mute circuit is disabled and the
output circuit is active.
7. Thermal shutdown
If the chip temperature rises above 150℃, then the thermal shutdown (TSD) circuit will be activated
and the output current will be mute.
8. Output voltage
The voltage booster circuit of (VSYS1) can be configured with external component as follows.

9. Driver gain
Driver input resistance is 10KΩ for CH1, CH3, CH4 and input resistance of CH2 is 7.5KΩ. Driver
gain can be set by using an external resistor and applying the following equations.
10. Short-circuit protection function
When the output of error amplifier is “H”, if the voltage of SPRT terminal has reached 1.265V upon
charging the terminal, switching of SW terminal will be disabled. Switching off time depends on the
value of the capacitor at SCP:
