BD6231F-E2

General Description

These H-bridge drivers are full bridge drivers for brush

motor applications. Each IC can operate at a wide range

of power supply voltages (from 6V to 32V), with output

currents of up to 2A. MOS transistors in the output stage

allow PWM speed control. The integrated VREF voltage

control function allows direct replacement of discontinued

motor driver ICs. These highly efficient H-bridge driver

ICs facilitate low-power consumption design.

Features

 Built-in, selectable one channel or two channels

configuration

 VREF voltage setting pin enables PWM duty control

 Cross-conduction prevention circuit

 Four protection circuits provided: OCP, OVP, TSD and

UVLO

Applications

VTR; CD/DVD players; audio-visual equipment; optical

disc drives; PC peripherals; OA equipments
