4-Channel CD Motor Driver

Sony Semiconductor 

4-Channel CD Motor Driver

Description

CXA2534Q is a 4-channel H-bridge motor driver IC

designed for portable CD systems. It has a built-in

DC to DC converter controller that allows voltage

step-up to typically 3.2 V; this voltage can be used

to power the system DSP, SSP and micro-controller.

In addition, it also provides a PWM regulated power

supply to the H-bridge output stage so as to ensure

high efficiency.

Features

• 4 channels of H-bridge drivers

• PWM regulated power supply for H-bridge output

stages

• Step-up DC to DC converter controller for system

power supply

• Start and off controls with soft start capability

• Reset pulse

• Short circuit protect

• Over-voltage protect

• Low battery voltage detection

• Rechargeable battery charger

• General purpose operational amplifier

• Thermal shut-down for battery charger and H-

bridge driver (170 °C/140 °C)

• Direct interface with wired remote controller

possible

Applications

Portable CD player
