Description

●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

●▪Internal UVLO and thermal shutdown circuitry

●▪Crossover-current protection
