Designed for pulse-width modulated (PWM) current control of two dc motors, the A3974SED is capable of output currents to
±1.5 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.
