Quad DMOS Full-Bridge PWM Motor Driver IC

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.
