UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
This pin is a status output. PB_OUT is used as the wake-up interrupt to an application processor based on the status of PB_IN. If PB_IN=LOW, PB_OUT = LOW (after 50-ms debounce). If PB_IN=HIGH, PB_OUT= high impedance (HIGH).
The pullup resistor for this open-drain output must not be connected directly to the battery as this may cause a leakage path when the power path (SYS) is turned off.
