We are using BQ25180 with a LiFePo4 battery and have to change different I2C registers each time the charger is powered up. After a Battery undervoltage event for example the registers are reset to default values again. Most problematic is Regulation Voltage VSET what is then set to 4.2V where the charge cutoff for LiFePo4 is only 3.6V.
In Datasheet I find
8.3.11 Software Reset
...Any bits loaded through OTP memory...
My question is if and how OTP memory can be preset to customer specific values?
Thanks,
Sven
