TPS2663: eFuse limitation at OV

Part Number: TPS2663

Hi Team,

Our customer has following question:

Is V_OVC parameter = 35V max. fixed ? Can load current induce any variation?
Is V_OVC at current loads of 0.5 / 1 / 2 A etc. the same? (i.e. 35V max.).
Any reason for having just 1mA load as test condition in datasheet? Why not some more appropriate load?

Best Regards,
Alex

Hi Alex,

The clamping performance will be poor at light load, that's the reason we provided at 1mA. At higher load currents, the max clamp voltage will be lower than 35V. Hope this answers your question.

Best Regards
