Product Description

The UDN2916B, UDN2916EB, and UDN2916LB motor drivers are 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 750 mA. The outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA).
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.
FEATURES
■ 750 mA Continuous Output Current
■ 45 V Output Sustaining Voltage
■ Internal Clamp Diodes
■ Internal PWM Current Control
■ Low Output Saturation Voltage
■ Internal Thermal Shutdown Circuitry
■ Similar to Dual PBL3717, UC3770
