TPS562201: TPS562201 OCP and Short protect sequence and active time issue

Hi Lanjie,

Here is the waveform I captured when OCP is trigger on TPS562201. The hiccup time is around 15ms.

Hi Antony:
thanks!
could you help check Hiccup wait time and the short happen to the protection start time.
the 1.8ms Hiccup time is design parameter or test parameter?
the part can keep safe with longtime high energy infush?

Hi Lanjie,

1.8ms wait time is tested parameter. If high energy infush means inrush output current, yes, our device could survive. The LSF will continuously on until inductor is discharged to the level lower than OCL.

Best,
Anthony

Hi Anthony:
When the output shorted, how long the time is when the part response to the protection function(反应时间，即从输出短路到芯片进入保护的过程，时间是固定的吗）

Hi Lanjie,

Sorry for the late response due to the Chinese New Year holiday. The delay time is fixed and here is the description in the datasheet.

Best,

Anthony
