4.3.1.12 Push Button Input (PB)
The PB pin is a CMOS-type input used to power-up the PMIC. Typically, the PB pin is connected to a momentary switch to ground and an external pullup resistor. The power-up sequence is triggered if the PB input is held low for 600 ms.
Figure 4-15 Left: Typical PB Input Circuit
Right: Push-Button Input (PB) Deglitch and Power-Up Timing
In ACTIVE mode, the TPS65216 monitors the PB input and issues an interrupt when the pin status changes, such as when it drops below or rises above the PB input-low or input-high thresholds. The interrupt is masked by the PBM bit in the INT_MASK1 register.
Figure 4-16 PB Input-Low or Input-High Thresholds NOTE
Interrupts are issued whenever the PB pin status changes. The PB_STATE bit reflects the current status of the PB input. nWAKEUP is pulled low for 150 µs on every falling edge of PB.
