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. 39 PWM 1 38 37 1 36 35 34 33 GND Data Sheet 29319.22† SENSE 1 PHASE 1 VREF 1 ENABLE 1 42 OUT 1A OUT 1B θ 1 43 41 RC1 E1 I10 I11 44 GND 7 8 9 10 11 12 13 EN1 VCC 40 6 5 4 3 2 1 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.
