Product Summary

The UDN2916B-T is a dual full-bridge PWM motor driver. The UDN2916B-T 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 750 mA. The UDN2916B-T outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA).

Parametrics

UDN2916B-T absolute maximum ratings: (1)Motor Supply Voltage, VBB: 45 V; (2)Output Current, IOUT(Peak): +1.0 A; (Continuous): +750 mA; (3)Logic Supply Voltage, VCC: 7.0 V; (4)Logic Input Voltage Range, VIN: -0.3 V to VCC+0.3 V; (5)Output Emitter Voltage, VE: 1.5 V; (6)Operating Temperature Range, TA: -20 to +85℃; (7)Storage Temperature Range, TS: -55 to +150℃.

Features

UDN2916B-T features: (1)750 mA Continuous Output Current; (2)45 V Output Sustaining Voltage; (3)Internal Clamp Diodes; (4)Internal PWM Current Control; (5)Low Output Saturation Voltage; (6)Internal Thermal Shutdown Circuitry; (7)Similar to Dual PBL3717, UC3770.
