Overview
UDN2916A STEPPER MOTOR DRIVER ADVANCE DATA ABLE TO DRIVE BOTH WINDINGS OF BIPOLAR STEPPER MOTOR OUTPUT CURRENT UP TO 750mA EACH WINDING WIDE VOLTAGE RANGE 10V TO 50V HALF-STEP, FULL-STEP AND MICROSTEPPING MODE BUILT-IN PROTECTION DIODES INTERNAL PWM CURRENT CONTROL LOW OUTPUT SATURATION VOLTAGE DESIGNED FOR UNSTABILIZED MOTOR SUPPLY VOLTAGE INTERNAL THERMAL SHUTDOWN 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.
BLOCK DIAGRAM Powerdip 20+2+2 ORDERING NUMBER: UDN2916A A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction.
