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 discontinued motor driver ICs. These highly efficient H-bridge driver ICs facilitate low-power consumption design.
Features
Built-in one channel configuration VREF Voltage Setting Pin Enables PWM Duty Control Cross-Conduction Prevention Circuit Four Protection Circuits Provided: OCP, OVP, TSD
and UVLO
