A4990 driver equivalent, automotive dual full-bridge driver.
* 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 .
Each full bridge uses DMOS power devices with integrated freewheeling diodes. Control circuits prevent cross-conduction.
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, .
