Integrated Circuit Chip A4989SLDTR-T Dual Full Bridge MOSFET Driver IC TSSOP38

Product Description Of A4989SLDTR-T

A4989SLDTR-T 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.
A4989SLDTR-T contains two sinusoidal DACs that generate the reference voltage for two separate fixed-off-time PWM current controllers. These provide current regulation for external power MOSFET full-bridges.
