Dual Full-Bridge MOSFET Driver

A4989 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 con

A4989 General Description

The A4989 is a dual full-bridge gate driver with integrated microstepping translator suitable for driving a wide range of higher power industrial bipolar two-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. .
