Hi,

Customer would like to know the sink current capability of the PG pin. Do you have the spec for it?

Best regards,

Hi Randy,

We don't have detail spec. As the datasheet says below,

The PGOOD pin is capable of sinking about 5mA current. As higher current can lead to higher voltage on PGOOD pin, which may lead to wrong logic status.

Sam
