Reversed voltage on Li-ion connection (P6)

Hello,

I attached an Adafruit li-ion battery to the P6 connector on my NPM1100-EK before I realized that Adafruit has their polarity opposite of the NPM1100's.

The LED on the nPM1100 instantly turned off and hasn't turned on since.  However, the LED is not burned out.  I'm assuming I've irreparably damaged the nPM1100 but wanted to see if there was a soft reset on the chip.

Thanks

  • I made exactly the same mistake using the P6 connector - the nPM1100-EK appears to be wired the opposite way around to common battery packs.

    The instantaneous effect, after connecting a battery the *correct* way around, appeared to be that VOUTB followed the VBAT voltage.

    However my nPM1100-EK seems to have made a miraculous recovery after sitting idle and unconnected for a few days.

    (although - obviously - it cannot now be "trusted")
