A4985 DMOS Microstepping Driver

A4985 Description

A4985 DMOS Microstepping Driver with Translator and Overcurrent Protection .
The A4985 is a complete microstepping motor driver with built-in translator for easy operation.

A4985 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 ▪ Thin profile QFN and TSSOP packages ▪ Thermal shu

A4985 Applications

* where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4985 automatically selects the current decay mode, Slow or Mixed. In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to
