BD6211F-E2

罗姆IC

General Description

These H-bridge drivers are full bridge drivers for brush

motor applications. Each IC can operate at a power

supply voltage range of 3.0V to 5.5V, 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 one channel 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
