D w w w SENSE 1 PHASE 1 VREF 1 ENABLE 1 2 91 7 DUAL FULL-BRIDGE PWM MOTOR DRIVER The UDN2917EB motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors.
Both 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.
Two logic-level inputs select output current limits of 0, 33%, 67%, or 100% of the maximum level.
A PHASE input to each bridge determines load current direction.
Active-low ENABLE input...
