Hi,
We have DDR5 application may have peak 79.7A inrush current about 20~30us, does TPS25981x have any possible to avoid this inrush current trig OCP?
Seem the maximum inrush current can avoid is 2x ILIM, right? thanks!
Thanks!
Jeff

Hi Jeff,
I apologies for the delayed response.
Did you get any solution?
TPS25981 device have both scalable Fast Trip (SFT) and Fixed Fast Trip (FFT). FFT threshold is 39.5A and SFT is 2*ILIM.
Can you confirm, the device is not triggering the circuit breaker for this inrush current event and you want OCP to trigger.
Can you share the schematic.
Best Regards,
Arush
