(1) 2.7 V is the minimum threshold for the battery at which the device will turn OFF. However, the minimum voltage at which the device will

power ON is 3.2 V ±100 mV (if PWRON does not have a switch and is connected to VBAT) considering battery plug as the device

switch on event. If PWRON has a switch then 3.2 V is the minimum for the device to turn ON.
