3961 Description
3961 DUAL FULL-BRIDGE PWM MOTOR DRIVER 3961 Designed for pulse-width modulated (PWM) current control of bipolar stepper motors, the A3961S is capable of continuous output currents to ±800 mA and operating voltages to 45 V. Internal fixed off-time PWM current-control circuitry can be used to regulate the maximum load current to a desired value. An internal precision voltage reference is provided to improve motor peak...
