The functions associated with each pin of ULN2003 along with pin names are shown in the table given below.

ULN2003 Pinout is shown in the below figure:.

I have also given the link to a reliable source, from where you can buy ULN2003 IC.

HereвЂ™s the link to download ULN2003 datasheet, must read it once.

Other than I/O Pins, we have Ground Pin where we need to provide 0V & Vcc (Common) Pin.

In the below figure, you can see ULN2003 has 16 Pins, where inputs and their respective outputs are placed in front of each other(for ease of circuit designing).

Similarly, the maximum output voltage of each Darlington pair is 50V.

Each Darlington pair can handle a maximum 500mA load, while the peak value is 600mA.

In simple words, we have 7 drivers in a single ULN2003 chip and thus can control a maximum of 7 loads.ULN2003 is a 16 Pin IC, consisting of 7 Darlington pairs (each pair protected with suppression diode) and thus has the capability to handle a maximum of 7 loads(could be inductive).Now, letвЂ™s have a look at whatвЂ™s inside ULN2003 in detail: ULN2003: Definition You should also have a look at Relay Interfacing with Microcontroller using ULN2003A. So, we can control different types of loads with ULN2003 i.e. Remember, the relay is also an inductive load. In this case, the Microcontroller is sending a signal to ULN2003, which then forwards it to relays (connected at output). For heavy motors, we normally use relays in between ULN2003 & motor. As its current rating is not that high, so itвЂ™s used to control small motors. If we check its datasheet, then we can see that ULN2003 can handle up to 50V & 500mA. There are different types of motor drivers available and ULN2003 is one of them.

Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).Д«ecause of these two reasons, we have to use the driver in between the microcontroller & motor.

First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).

Why do we need to use drivers? We use drivers (to control motors) because of two reasons. PIC, Arduino etc.), then you must have heard about drivers. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. If you have ever controlled any motor (i.e. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. Today, I am going to give you a detailed Introduction to ULN2003. Hello everyone! I hope you will be absolutely fine and having fun.
