ULN2003 (NPN Darlington Transistors 7- Array )

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
  • 16-pin DIP

Note: Complete Technical Details can be found at the ULN2003 datasheet given at the end of this page.

Where to use a ULN2003

This IC is commonly used to drive Relay modules, Motors, high current LEDs and even Stepper Motors. So if you have anything that anything more than 5V 80mA to work, then this IC would be the right choice for you.

How to use a ULN2003 IC

The ULN2003 is a 16-pin IC. It has seven Darlington Pairs inside, where each can drive loads up to 50V and 500mA. For these seven Darlington Pairs we have seven Input and Output Pins. Adding to that we can a ground and Common pin. The ground pin, as usual is grounded and the usage of Common pin is optional. It might be surprising to note that this IC does not have any Vcc (power) pin; this is because the power required for the transistors to work will be drawn from the input pin itself. The below circuit is a simple circuit that can be used to test the working of ULN2003 IC.
