Part Number: LP8862-Q1

My customer have a question.

Could you please let me know about the SD and VSENSE_N pins when they don't use power line control function.

Is the following condition no problem?

- SD = Open

- VSENSE_N = Vin

Thanks

Hi Mukuno-san,

Yes, it won't have any issue.
Input current sense resistor can be still used while PL FET is not used, so VSENSE_N pin can be connected to low side of sense resistor(if used) or directly to Vin.
If input current sense resistor is used without PL FET, it can't disconnect Vin at OCP case, but can stop boost and LED driver channels at least
