A3983 Overview
The A3983 is a plete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A3983 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes.
A3983 Key Features
- 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
