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
