H-bridge Drivers for Brush Motors
H-bridge Drivers
(VREF Series)
BD621□Series,BD622□Series,BD623□Series
●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 3V to 36V), 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.
