The A3982 is a complete stepper motor driver with built in translator for easy operation. It is designed to operate bipolar stepper motors in full- and half-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3982 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
