The input overvoltage protection protects the device and downstream components connected to SYS, and BAT against damage from overvoltage on the input supply. When VIN > V­_{IN_OVP}, a VIN overvoltage condition is determined to exist. During the VIN overvoltage condition, the device turns the battery discharge FET on,the STAT1 and STAT2 pins update to reflect a recoverable fault (STAT1 = LOW, STAT2 = HIGH). Once the VIN overvoltage condition is removed, the STAT1 and STAT2 pins update to normal operation once the startup routine has finished due to a power good VIN detection . Thereafter VIN powergood condition is determined if VIN > VBAT + VSLEEP.
