BQ25505: Maximum voltage on #EN pin

Part Number: BQ25505

Hi,

What is the maximum voltage allowed on #EN pin of the BQ25505?

Is it OK to have VEN > VBAT_SEC?

Regards

Giuliano

    Hi Giuliano,

    We haven't tested that condition.  I do not expect IC damage unless the voltage is above the 5.5V abs max but it is likely that the EN pin will sink current higher than its quiescent current.

    Regards,
