Devices are useful for driving a wide range of loads including solenoids, relays DC motors, LED displays filament lamps, thermal printheads and high power buffers. ULN2003 interface to logic families such as 5V TTL, CMOS. Suppression diodes are included for inductive load driving and inputs are pinned opposite to outputs to simplify board layout. Each channel rated at 500mA and can withstand peak currents of 600mA. Array contains seven open collector and darlington pairs with common emitters. It can be used a test switch, meaning when this pin is grounded all the output pins will be grounded.The ULN2003APG is a high voltage, high current seven darlington transistor array. The COM pin is connected to ground through a switch, this connection is optional. However, by combining two or more output pins to gather, you can run higher current loads. Each load connected to the output pin must be no more than 50C and 500mA. This ULN2003ADR consists of 7 NPN Darlington pairs which features. When the LED's negative terminal is grounded, the circuit is completed, and the LED glows. The ULN2003A Series devices are high voltage, high current Darlington transistor arrays. This is because when the IC's input pin goes heavy, the corresponding output pin goes to earth. The LED's positive pin is connected to the positive load voltage, while the negative pin is connected to the IC's output pin. The circuit below is a basic circuit that can be used to evaluate the ULN2003 IC's functionality.Ĭonsider the LEDs to be the loads in the circuit, and the logic pins (blue color) to be the pins attached to the digital circuit or microcontroller like the Arduino. It can come as a surprise that this IC lacks a Vcc (power) pin this is due to the fact that the power needed for the transistors to function will be drawn from the input pin itself.

Suppression diodes are included for inductive load driving and the inputs are pinned opposite the outputs to simplify board layout. Each channel is rated at 500 mA and can withstand peak currents of 600 mA. The ULN2003 is high-voltage high-current Darlington transistor arrays each containing seven open collector common emitter pairs. The ground pin is grounded as is customary, and the use of the Common pin is optional. The ULN2003 is high-voltage, high-current Darlington arrays each containing seven open collector Darlington pairs with common emitters. We may also add a ground and a common pin to the mix. We have seven Input and Output Pins for these seven Darlington Pairs. 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. It contains seven Darlington Pairs, each capable of driving loads up to 50V and 500mA. The collector-current rating of a single Darlington pair is 500 mA. The ULN2003 is a 16-pin integrated circuit. The ULN2003A is a high-voltage, high-current Darlington transistor array consisting of seven NPN Darlington pairs that featurehigh-voltage outputs with common-cathode clamp diodes for switching inductive loads.
