Description
●The A3984 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3984 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.
●Features and Benefits
●▪Low RDS(ON) outputs
●▪Automatic current decay mode detection/selection
●▪Mixed and Slow current decay modes
●▪Synchronous rectification for low power dissipation
●▪Internal UVLO and thermal shutdown circuitry
●▪Crossover-current protection
