BQ24195: pull-up resistor for STAT pin

K.Yaita

Part Number: BQ24195

Hi Team,

The datasheet shows "Connect to the pull up rail via 10-kΩ" for STAT pin.

On the other hand, 9.2 Typical Application (page.34) shows 2.2kΩ for pull-up resistor.
Which do you recommend?
Is there minimum value?

Hey K. Yaita,

We use a 2.2kOhm resistor because we use an LED to indicate the charge status visually. Thus, we need a stronger pull-up for higher current.

However, a 10k is sufficient if the STAT pin is only connected to a controller/processor.
