Part Number: ULN2003A Hi team, I'd like to know about the difference between ULN2003A and ULN2003AI for VOH. Why is there a difference between Vs-50mV and Vs-20mV? Does the internal structure make a difference? BR, Kengo.
Part Number: ULN2003A Hi expert,
Customer would like to use darlington transistor array ULN2003A for Pan/Tilt control in IP Camera. The stepper motor is 5V / 20ohm and 4phase/5wire. Each phase current would be 250mA and there might be two phases operate…
Part Number: ULN2003A I am using ULN2003a to drive multiple LED and controlling it directly through controller. I want to know what is the min voltage I can apply at the imput(base) terminal to start the function. Or say V(IH) value?
Part Number: ULN2003A Hi
The datasheet mentioned collector current = 500mA and showing below is my understanding of this definition.
Notice there is another parameter, output clamp current (Iok), could you advise how is the current flowing path?
R…
Hi Nathan,
This is indeed strange, something that would help a lot here is a waveform showing Vrelay+, Vrelay-, and COM of both a working and not working relay when COM is floating, as well as a relay when COM is floating.
Unfortunately, it's hard to diagnose…
Part Number: ULN2003A We are using ULN2003ADR in one of our existing design for 12V relay driving, the controller is ATmega2560 and operationg voltage is 5V. Currently we are planning to change the controller to MGM240 which is working in 3.3V.So we need…
Part Number: ULN2003A Hi,
I have a customer using ST microelectronics‘s ULN2003D.
May I ask which package of TI ULN2003 is recommended to be compatible?
Many thanks~
Part Number: ULN2003A Hi Team,
our datasheet specifies 100uA as collector cutoff current ICEX at VCE=50V.
Can you also say something about max value at VCE of 6V and 60 degC ambient?
Regards
Andreas

Part Number: ULN2003AI Other Parts Discussed in Thread: ULN2003A , ULQ2003A Hi team, ULQ2003A and ULN2003A have different temperature ranges. Some temperature-dependent SPECs are different, but the SPECs at room temperature(Ta = 25C) are the same. Does this…
