Datasheet
DC Brush Motor Drivers (36V max.)
BD623xxx Series
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 deprecated
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
