UNLESS OTHERWISE NOTED, this document contains PRODUCTION DATA.
This pin is an input to the PMU which needs to be pulled HIGH for the PMU to stay in POWER ON_2-state once PB_IN is released. Once this pin is pulled LOW while PB_IN=LOW, the PMU is shutting down without delay, turning off the DCDC converters and the LDOs. If POWER_ON is pulled HIGH while there is power at USB or AC, the TPS6507x will enter POWER ON_2-state and start the DC-DC converters and LDOs according to the sequence programmed. See Figure 34.
