Hi,
I used bq25790 for 2S 18650/3500mAh batteries charging, setting PROG resistor 8.2k.
The batteries were completely charged initially (totally up to 8.4V), providing the same voltage to 25Ohm system load.
After switching the external PS off they slowly dischaged down to VBAT=5.72V and VSYS=5.71V and didn't stop.
- Does bq25790 have hardware / built-in under voltage protection (UVP) and what its default level is?
- What internal settings/registers might be used to change the UVP level?
Thanks,
Semion
