LOGIC SUPPLY
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.
