2918 OUT1A OUT2A E2 OUT2B LOAD SPLY SENSE 2 1 2 3 4 5 6 7 8 9 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 protection against inductive transients.
