Max sink current of LT8606 PG (Power Good) pin


What is the maximum sink current of LT8606 PG (Power Good) pin? Unfortunately, datasheet does not specify this value. I would like to use PG pin to discharge the remaining voltage after power off.

Thank you.

  • 0.1VPG voltage is used for measuring current into PG pin to calculate the PG to GND resistance. You are correct in computation but that doesn’t mean PG can only handle ~100uA. For short time, PG handle higher current without damaging the part. For long time, it’s limited by thermal. Unfortunately we don’t have data for this MAX PG current. MAX DC current PG may be able handle should be between 1~10mA.
