AT5801
Preliminary Product Information
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.
