ULN2003 IC is one of the most commonly used Motor driver IC generally used when we need to drive high current loads using digital logic circuits like Op-maps, Timers, Gates, Arduino, PIC, ARM etc.
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
ULN2003 IC is one of the most commonly used Motor driver IC generally used when we need to drive high current loads using digital logic circuits like Op-maps, Timers, Gates, Arduino, PIC, ARM etc. For example a motor that requires 9V and 300mA to run cannot be powered by an Arduino I/O hence we use this IC to source enough current and voltage for the load.
