UDQ2917 Datasheet (Allegro MicroSystems) - DUAL FULL-BRIDGE PWM MOTOR DRIVER

UDQ2917, DUAL FULL-BRIDGE PWM MOTOR DRIVER

2 91 7 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 1.5 A.
