ULN2803A www.ti.com SLRS049H–FEBRUARY1997–REVISEDFEBRUARY2017 8 Detailed Description 8.1 Overview This standard device has proven ubiquity and versatility across a wide range of applications. This is due to its integrationof8Darlingtontransistorsthatarecapableofsinkingupto500mAandwideGPIOrangecapability. The ULN2803A is comprised of eight high voltage, high current NPN Darlington transistor pairs. All units feature a common emitter and open collector outputs. To maximize their effectiveness, these units contain suppression diodes for inductive loads. The ULN2803A has a series base resistor to each Darlington pair, thus allowing operation directly with TTL or CMOS operating at supply voltages of 5 V or 3.3 V. The ULN2803A offers solutions to a great many interface needs, including solenoids, relays, lamps, small motors, and LEDs. Applications requiring sink currents beyond the capability of a single output may be accommodated by paralleling theoutputs. 8.2 Functional Block Diagram COM 2.7kΩ Output C Input B 7.2 kΩ 3 kΩ E 8.3 Feature Description Each channel of ULN2803A consists of Darlington connected NPN transistors. This connection creates the effect of a single transistor with a very-high current gain. The very high β allows for high output current drive with a very-lowinputcurrent,essentiallyequatingtooperationwithlowGPIOvoltages. The GPIO voltage is converted to base current through the 2.7-kΩ resistor connected between the input and baseofthepredriverDarlingtonNPN. The diodes connected between the output and COM pin are used to suppress the kick-back voltage from an inductive load that is excited when the NPN drivers are turned off (stop sinking) and the stored energy in the coilscausesareversecurrenttoflowintothecoilsupplythroughthekick-backdiode. In normal operation, the diodes on base and collector pins to emitter will be reverse biased. If these diode are forward biased, internal parasitic NPN transistors will draw (a nearly equal) current from other (nearby) device pins. 8.4 Device Functional Modes 8.4.1 InductiveLoadDrive When the COM pin is tied to the coil supply voltage, ULN2803A is able to drive inductive loads and suppress the kick-backvoltagethroughtheinternalfreewheelingdiodes. 8.4.2 ResistiveLoadDrive When driving resistive loads, COM can be left unconnected or connected to the load voltage supply. If multiple suppliesareused,connecttothehighestvoltagesupply. Copyright©1997–2017,TexasInstrumentsIncorporated SubmitDocumentationFeedback 9 ProductFolderLinks:ULN2803A

When this is the case, make sure that the output voltage does not heavily exceed the COM pin voltage. This will heavily forward bias the flyback diodes and cause a large current to flow into COM, potentially damaging the on- chipmetaloroverheatingthepart. 11 Layout 11.1 Layout Guidelines Thin traces can be used on the input due to the low current logic that is typically used to drive ULN2803A. Take care to separate the input channels as much as possible, as to eliminate crosstalk. TI recommends thick traces for the output, in order to drive high currents as desired. Wire thickness can be determined by the trace material'scurrentdensityanddesireddrivecurrent. Because all of the channels currents return to a common emitter, it is best to size that trace width to be very wide.Someapplicationsrequireupto2.5A. 11.2 Layout Example 1B 1 18 1C 2B 2 17 2C 3B 3 16 3C 4B 4 15 4C 5B 5 14 5C 6B 6 13 6C 7B 7 12 7C 8B 8 11 8C GND 9 10 COM GND Figure15.
