AT5801

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:
