A2917SEB General Description

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 modula tion (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 inputs control the four drivers in each bridge.FEATURES ■ 1.5 A Continuous Output Current ■ 45 V Output Sustaining Voltage ■ Internal Clamp Diodes ■ Digital Control of Output Current ■ Internal Thermal Shutdown Circuitry ■ Similar to Dual PBL3770
