The undervoltage (UV) protection detects low voltages on the PVDD and VBAT pins. In the event of an UV condition, the FAULT pin is asserted and the I2C register is updated. A power-on reset (POR) on the VDD pin causes the I2C to goes to the high-impedance (Hi-Z) state and all registers are reset to default values. At power-on or after a POR event, the POR warning bit and WARN pin are asserted.
