A4984 DMOS Microstepping Driver

A4984 Description

A4984 DMOS Microstepping Driver with Translator and Overcurrent Protection .
The A4984 is a complete microstepping motor driver with built-in translator for easy operation.

A4984 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

A4984 Applications

* where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4984 automatically selects the current decay mode, Slow or Mixed. 24-pin TSSOP with exposed thermal pad (LP Package) Continued on the next page… Microcontroller or Controller
