Internal circuit diagram of uln 2003 having different resistors and diodes is shown in the figure below.

Uln2003 logic diagram. This ic comes in handy when we need to drive high current loads using digital logic circuits like op maps timers gates arduino pic arm etc. This article includes everything you need to know about controlling a 28byj 48 stepper motor with the uln2003 driver board and arduino. It features common cathode flyback diodes for switching inductive loads. Uln2001 uln2002 uln2003 uln2004 diagram 17 1 diagram figure 1.

Where to use a uln2003. Input compatible with popular logic types. The uln2003a is a high voltage high current darlington transistor array consisting of seven npn darlington pairs that feature high voltage outputs with common cathode clamp diodes for switching inductive loads. High output voltage of around 50v.

Uln2001 general purpose dtl ttl. First we take a look at the easy to use arduino stepper librarythis library is great when you are just starting out but doesnt have many extra features. Here we will explore using the versatile uln2003a darlington transistor array with a typical micro controller such as arduino. Please try again later.

The uln2003a is an array of seven npn darlington transistors capable of 500 ma 50 v output. The uln2003 is a monolithic ic consists of seven npn darlington transistor pairs with high voltage and current capability. Tpic2701 uln2001 uln2002 uln2004 l293d motor driver shield. The figure below shows the internal circuit diagram of the uln 2003 with different resistors and diodes.

It is commonly used for applications such as relay drivers motor display drivers led lamp drivers logic buffers line drivers hammer drivers and other high voltage current applications.
