Part Number: TPS62811-Q1

Hi team,

Is there a recommended rage for pull up resistor on PG-pin?

Also, the datasheet shows 100kohm as an example, may I know the reason why it is 100k?

Best regards,

Hi Kurumi-san,

For the minimum pull-up resistor across PG pin, limit the max sink current to 2mA. Typically, 1Mohm would be maximum value to avoid external noise influencing the PG level.

I hope I was able to answer your queries.

Best regards,
