A3958SLBTR

Motor Driver 5V 24Pin SOIC W

Designed for pulse-width modulated PWM current control of dc motors, the A3958SB and A3958SLB are capable of continuous output currents to ±2 A and operating voltages to 50 V. Internal fixed off time PWM current-control timing circuitry can be programmed via a serial interface to operate in slow, fast, and mixed current-decay modes.
