Quad DMOS Full-Bridge PWM Motor Driver IC

Allegro MicroSystems Europe introduces a quad DMOS full-bridge driver IC 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.  Allegro’s 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. High-resolution microstepping control is possible via independent current control reference voltage inputs for each full bridge.
