BQ76PL455A-Q1: BQ76PL455A-Q1 / TOP pin current at ACTIVE mode

Part Number: BQ76PL455A-Q1

Hi,

I know that the TOP pin current is specified at IDLE mode as ISLEEP in EC. Then do you have also TOP pin current at ACTIVE mode? I'm not sure that IACTIVE means it because there is no comment of "into TOP pin" in description of IACTIVE.

Hello Satoshi,

I can confirm the IACTIVE parameter is into the TOP pin. Does that help clarify your question?

Hi David,

Thank you for your support. Yes, it'll be helpful if you comfirm the IACTIVE parameter is into the TOP pin.
Actually the customer would like to know the maximum quiescent current (worst case) while communicating.

Satoshi

Hi Satoshi,

IACTIVE is into the top pin.

It really depends on how many communications interfaces are running, and if there is load on the GPIOs. We typically say ~1mA per comm interface while running, which gives us ~8mA. If you go off of the worst case of 7mA while not communicating, we can say worst case of 10mA while communicating, but remember that is ONLY while data is being sent. The average current will be much lower.
