Product Summary
The A2918SWV is a dual full-bridge pwm motor driver. The A2918SWV is designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motor. All bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 1.5 A. For PWM current control, the maximum output current is determined by the user selection of a reference voltage and sensing resistor. A PHASE input to each bridge determines load current direction. Active low ENABLE inputs control the four drivers in each bridge.
