A3984 DMOS Microstepping Driver

A3984 Description

A3984 DMOS Microstepping Driver with Translator .
The A3984 is a complete microstepping motor driver with built-in translator for easy operation.

A3984 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 PACKAGE: 24-pin TSSOP with exposed thermal pad (suffix LP)

A3984 Applications

* where a complex microprocessor is unavailable or is overburdened. The chopping control in the A3984 automatically selects the current decay mode (Slow or Mixed). When a signal occurs at the STEP input pin, the A3984 determines if that step results in a higher or lower current in each of the motor ph
