A2918 - DUAL FULL-BRIDGE PWM MOTOR DRIVER

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 .
