Other Parts Discussed in Thread: BQ25618
I am using the BQ25616 as a power bank. (1) When 5V is applied to Vin, I charge the battery. No load connected to PMID or VSYS. (2) When the 5V at Vin is removed, Q1 turns off, keeping Vbat from connecting to Vin. The OTG (boost) remains off. (3) When I connect a load to PMID, with no voltage on Vin, I turn on the OTG (Boost) and provide 5V to the PMID load.
I would like to keep Q1 off when the OTG (Boost) is enabled. Is there any way to disable Q1 when in OTG (boost) mode and Vin = 0V?
