Automotive, Programmable Stepper Driver

The A3981 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and sixteenth-step modes, at up to 28 V and ±1.4 A. The A3981 can be controlled by simple Step and Direct \n• Low RDS(on) outputs, 0.5 Ω source and sink, typical \n• Mixed, Fast, and Slow current decay modes \n• Internal OVLO, UVLO, and Thermal Shutdown circuitry \n• Short circuit and open load diagnostics \n• Stall detect features \n• Highly configurable via SPI-compatible serial interface \n;
