BD621X-E Datasheet, PDF (1/21 Pages) Rohm – DC Brush Motor Drivers (7V max.)

Datasheet
DC Brush Motor Drivers (7V max.)
BD621xxx Series
●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 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
