Input overvoltage protection protects the device and downstream components connected to SYS, and BAT against damage from overvoltage on the input supply. The input overvoltage protection thresholds are dependend on VIN_OVP bit.When VIN > VIN_OVP, a VIN overvoltage condition is determined to exist. During the VIN overvoltage condition, the device turns the input FET OFF, battery discharge FET ON, sends a single 128-μs pulse on INT unless VIN_OVP_FAULT_MASK is set to be 1, and the fault bit (VIN_OVP_FAULT_FLAG) is updated over I2C. The VIN_PGOOD_STAT bit also is affected by the VIN overvoltage condition as the VIN power good (VIN_PGOOD) condition will fail. Once the VIN overvoltage condition is removed (VIN ≤ VIN_OVP - VIN_OV_HYST ), the VIN_OVP_STAT bit is cleared and the device returns to normal operation. Thereafter, a VIN power good (VIN_PGOOD) condition is determined if VIN > VBAT + VSLEEPZ_HYST and VIN > VIN_UVLO.
