CXA2534Q
4-Channel CD Motor Driver
Description
48 pin QFP (Plastic)
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

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
