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 drives.
