Product Details
| Description The A4983 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, eighth, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A. The A4983 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 ▪Crossover-current protection ▪ 3.3 and 5 V compatible logic supply ▪ Very thin profile QFN package ▪ Thermal shutdown circuitry |
