- ULN2003A - Wikipedia
The ULN2003A is an integrated circuit produced by Texas Instruments It consists of an array of seven NPN Darlington transistors capable of 500 mA, 50 V output It features common-cathode flyback diodes for switching inductive loads (such as servomotors)
- Introduction to ULN2003 - The Engineering Projects
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) In simple words, we have 7 drivers in a single ULN2003 chip and thus can control a maximum of 7 loads
- Everything You Ever Wanted To Know About The ULN2003
Each of the seven outputs works like this simplified diagram Inside the ULN2003 you’ll find seven high-voltage and high-current NPN Darlington pairs capable of switching inductive loads But
- ULN2003A - - High Voltage, High Current Darlington Transistor Arrays
The seven NPN Darlington connected transistors in these arrays are well suited for driving lamps, relays, or printer hammers in a variety of industrial and consumer applications Their high breakdown voltage and internal suppression diodes insure freedom from problems associated with inductive loads
