H-bridge Drivers for Brush Motors

7V Max.
H-bridge Drivers

BD621X Series

No.11007EDT01

●Description

These H-bridge drivers are full bridge drivers for brush motor applications. Each IC can operate at a range of power supply
voltages (from 3.0V to 5.5V), supporting output currents of up to 2A. MOS transistors in the output stage allow for PWM
signal control, while the integrated VREF voltage control function of previous models offers direct replacement of
deprecated motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.

●Features

1) Built-in one channel configuration

2) Low standby current

3) Supports PWM control signal input (20kHz to 100kHz)

4) VREF voltage setting pin enables PWM duty control

5) Cross-conduction prevention circuit

6) Four protection circuits provided: OCP, OVP, TSD and UVLO

●Applications

VCR; CD/DVD players; audio-visual equipment; optical disc drives; PC peripherals;
OA equipments

●Line up matrix
