Hi team,
My customer has are considering the ULN2003A in a new product development and had a question: . They have always used the ULN to switch 24V relays, now they would like to use this for 5V relays.
But then the VCE Saturation Voltage gets in the way: According to the data sheet, this is max. 1.1V at 100mA collector current.
But their relays operate at approx. 80mA. Can you perhaps find out what the maximum Vce-Saturation Voltage is at 80mA and 0 ° C? There is already a very helpful diagram in the data sheet, but unfortunately only for typical values and 25 ° C:
Can you please inform how high the VCE sat. @Tj 0-85°C at input of 4V/80mA is?
Thanks for the support,
BR, Obinna.
