I'm working on a water damaged switch that after cleaning has no shorts.
Correct voltages coming out of the max77620.
Initially it was only drawing 0.03 amps, so I changed the 2 max77621 second stage regulators and reflowed the max77620. And changed the bq and m92 (the water damage was around the bq and fuel gauge)
It now draws 0.125 amps, the 3.3v is also present coming from the regular above the audio ic.
I've removed the fuel gauge as this looked damaged, don't have another to hand but powered on without it and still draws 0.125
I'm not expecting it to switch on without the fuel gauge but what should the current draw be without it?
