Description:
Dmos dual full-bridge microstepping pwm motor driver.
Datasheet Details
Designed for pulse width modulated (PWM) current control of bipolar microstepped stepper motors, the A3992 is capable of continuous 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 the serial interface to ope
