Description

The UDN2916A is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors.

The UDN2916A with a few external components form a complete control and drive circuit for LSTTL or microprocessor controlled stepper motor  system.

The power stage is a dual full bridge capable of sustaining 50V and including four diodes for current recirculation.

A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction.

An internal pulse-width-modulation (PWM) controls the output current to 750mA with peak startup current up to 1A.

Wide range of current control from 750mA (each bridge) is permitted by means of two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction.

A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.
