VBAT_INF

Battery Voltage Inflection Point. This is the VBAT sense value at which the limiter either

activates or starts reducing the threshold. It corresponds to the value that can be read

in the VBAT read only status register. To calculate this value in volts, refer to the VBAT

Sensing section. Voltage = 3.8 + 12.4 × Decimal Value/255.
