General Description

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.

The CMOS logic section provides four modes of operation: forward and reverse normal drive rotation, outputs-off free spin (coast), and electronic braking.
