A3986 - Dual Full-Bridge MOSFET Driver

Description

The A3986 is a dual full-bridge gate driver with integrated microstepping translator suitable for driving a wide range of higher power industrial bipolar 2-phase stepper motors (typically 30 to 500 W).

Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.

Features

  • 2-wire step and direction interface Dual full-bridge gate drive for N-channel MOSFETs Operation over 12 to 50 V supply voltage range Synchronous rectification Cross-conduction protection Adjustable mixed decay Integrated sinusoidal DAC current reference Fixed off-time PWM current control.
