Detailed Product Description

A4989SLDTR-T IC MTR DRV BIPOLR 3-5.5V 38TSSOP Allegro MicroSystems

Product Details

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 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 and Benefits

▪ 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
▪ Enhanced low current control when microstepping
▪ Pin compatible with the A3986
