DUAL FULL-BRIDGE PWM MOTOR DRIVER
The A2918SWH and A2918SWV motor drivers are designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors.
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’s 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.
The bridges include both ground clamp and flyback diodes for...
