The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
The four inputs (IN1 to IN4) can control a bipolar stepper motor in full or half-step mode, or DC motors in forward, reverse, or brake mode.
The inputs can be pulsewidth modulated for current or speed control at frequencies up to 250kHz.
Internal protection circuitry includes thermal shutdown (TSD) and crossover (shoot-through) protection.
The A3901 is supplied in an RoHS compliant 3 x 3 x 0.75mm nominal, 10-lead MLP package with an exposed thermal pad.
