ULN2003 driver chip, 500mA

A. B. C. D LED indicating the four phase stepper motor working status.

ULN2003 Features:

•     Contains 7 high-voltage and high current Darlington pairs
•     Each pair is rated for 50V and 500mA
•     Input pins can be triggered by +5V
•     All seven Output pins can be connected to gather to drive loads up to (7×500mA) ~3.5A.
•     Can be directly controlled by logic devices like Digital Gates, Arduino, PIC etc
•     Available in 16-pin DIP, TSSOP, SOIC packages

ULN2003 IC is one of the most commonly used Motor driver IC generally used when needed to drive high current loads using digital logic circuits like Op-maps, Timers, Gates, Arduino, PIC, ARM etc.
