A2918SWH DUAL FULL-BRIDGE PWM MOTOR DRIVER

Data Sheet 29319.24A 2918 DUAL FULL-BRIDGE PWM MOTOR DRIVER The A2918SWH and A2918SWV motor drivers are designed OUT1A 1 OUT2A 2 E2 3 OUT2B 4 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. LOAD SPLY 5 2 For PWM current control, the maximum output current is TSD PWM 1 VREF PWM 2 VCC 1 VBB SENSE2 6 ENABLE2 7 P.
