General Description

The A5990 is a quad DMOS full-bridge driver capable of driving up to two stepper motors or four DC motors.

Each full-bridge output is rated up to 1.6 A and 40 V.

The A5990 includes fixed off-time pulse-width modulation (PWM) current regulators, along with 2- bit nonlinear DACs (digital-to-analog converters) that allow stepper motors to be controlled in full, half, and quarter steps, and DC motors in forward, reverse, and coast modes.
