Part Number: ULN2003A Hi team,
Our customer is conducting electrostatic discharge (ESD) testing on the ULN2003A. During this testing, a failure of the ULN2003A has been observed.
Load: Relay Phenomenon: When ESD is applied, the electrostatic discharge…
Part Number: ULN2003A Tool/software: HI sir
we use the ULN2003 over 20 years, no any issue before
now, we meet 5% fail rate in the parts. old date code is ok, new data code fails
may i know what any PCN released?
thanks
Part Number: ULN2003A We have been using these IC for years in our UPS to drive the relays, last week found these IC burnt during Unit functional testing, after that we changed over to old batch code no failures. same topic found in forum similar issue…
Part Number: ULN2003A Tool/software: I am using this to drive stepper motor and having sudden voltage drop at output. there is constant 12V supply and getting proper signal from MCU.
I wanna understand what the reason behind this is
attaching waveform…
Part Number: ULN2003A Other Parts Discussed in Thread: ULN2004A Tool/software: Hello guys,
One of my customers is considering using ULN2003A instead of ST ULN2064B.
ULN2064B https://www.st.com/content/ccc/resource/technical/document/datasheet/07/e7…
Part Number: ULN2003A 1. In the ULN2003A Figure 5-5, does the maximum collector current graph show the value per channel? (For example, when N=4, 70°C, and DUTY=100%, the maximum value per channel is approximately 57mA. 57mA x 4 = 228mA in total.) 2.…
Part Number: ULN2003A 7.4.2 Resistive Load Drive When driving a resistive load, a pullup resistor is needed in order for ULN2003A device to sink current and for there to be a logic high level. The COM pin can be left floating for these applications. …
Part Number: ULN2003A Hello team,
My customer is considering to change the package of ULN2003A (PW to DYY). For this, customer want to refer the below figure and compare of PW and DYY. Can you prepare the figure in case of PW or tell me how to calculate…
Part Number: ULN2003A Dear
For ULN2003ADR, we observed that after power-on, the device would restart and then burn out during our application process. For the UVLED, we used a linear constant current scheme. The current was 80mA. Could you please check…
