Product description
DMOS Stepper Motor Driver with Translator
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.
Features
* 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
