A4983 DMOS Microstepping Driver

A4983 Description

A4983 DMOS Microstepping Driver with Translator .
The A4983 is a complete microstepping motor driver with built-in translator for easy operation.

A4983 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 ▪ Crossover-current protection ▪ 3.3 and 5 V compatible logic supply ▪ Very thin profile QFN package ▪ Thermal shutdown

A4983 Applications

* where a complex microprocessor is unavailable or is overburdened. The chopping control in the A4983 automatically selects the current decay mode (Slow or Mixed). When a signal occurs at the STEP input pin, the A4983 determines if that step results in a higher or lower current in each of the motor ph
