A4990 Automotive Dual Full-Bridge Driver

The A4990 is a dual full-bridge driver for stepper motors and small brush DC motors in automotive applications. Each full bridge uses DMOS power devices with integrated freewheeling diodes. Control circuits prevent cross-conduction, or shootthrough, when switching between high-side and low-side driv.

A4990 Features

* Two full-bridge power outputs

* Typical application up to ±800 mA, 28 V

* Adjustable peak current limit control

* Minimum overcurrent shutdown at 1.4 A

* Continuous operation at high ambient temperature

* Synchronous rectification for low power dissi
