Does The Npm2100 Have Wakeup On Interrupt?

[SoldOutYungLean]

Planning on using the npm2100 PMIC as our PMIC for an upcoming asset tracking solution.

We will have an accelerometer that will determine when the main MCU (nrf54) wakes up, when the device gets moved.
However, we would also like to utilize the hibernation mode of the npm2100.

Will the npm2100 feature a wake-up GPIO that can be triggered? If not, what would be the fix?

Hello,

Sorry for the late reply.

The nPM2100 can wake up from hibernate mode either by using the wake-up timer, or by using the SHPHLD pin. During hibernate mode BOOST Vout is discharged and assuming nPM2100 is using its BOOST Vout to power the nRF54, the nRF54 will be powered down. In this case the only way to wake-up the asset tracker is either by an edge on the SHPHLD pin or by using nPM2100's wake-up timer. Please refer to section "7.4 Hibernate mode" in the attached nPM2100 preliminary datasheet for more details.
