STA6940M Datasheet (Sanken) - Brushed DC Motor Driver

STA6940M, Brushed DC Motor Driver

Combining low-power CMOS-compatible logic with highcurrent, high-voltage power MOSFET outputs, the STA6940M provides complete control and drive for brush DC motors.

It provides internal fixed off time, pulse-width modulation (PWM) control of the output current, rated for 4 A normal operating level.
