The A3982 is a complete stepper motor driver with builtin 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.
* Low R_DS(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
