BQ25606: PG and STAT pins

Dear all:

What is the maximum input current for the PG and STAT pin? I want to calculate the resistance I need to limit the current for an LED that has a forward voltage of 2.1V and needs 20mA.

    Hi Oscar,

    The maximum current for the STAT pin is 6 mA (Table 7.1 in the datasheet). As for the PG pin, a current just over 30 mA is a good value to design for. The PG pin is an active low power good indicator which outputs logic LOW to indicate a good input if (among other things) the input current limit is >30 mA (Sections 6 and 8.3.7.1 in the datasheet).

    Best Regards,
