nPM1300 high voltage output at VOUT2 upon VBAT connection.

[xproto]

My lipo battery is at 3.86V and I measured 3.76V at VOUT2 which supplies the nRF52832.

I just based the design in the example circuits in nPM1300 datasheet.

I already reviewed the circuit but I don't see any problem based on example. Based on the VSET2 R it should output 3.3V.

can you share the screenshot of PMIC on your PCB Design file

This is already modified but only for the I2C/VDDIO power from previous schematic I sent , I connected VDDIO/VDD to 3.3V as advised in datasheet.

Thats what in the example and datasheet says. It should directly tied to gnd or thru resistor. So I choose directly to Gnd as shown on example config. Let me see if I can cut trace and add a 10k R.

[Parth Parekh]

Yes, please do that and update me.

I cant cut the trace on pins auto generated by KiCAD it is underneath the chip already. But I tried with the nPM1300 dev board shorting the NTC to GND. It outputs 3.3V. So I think the is not the problem.

But without the 10K Res or NTC thermistor the PMIC wont Charge your battery. And also check if the AVSS pad is properly getting grounded.

I have confirmed this via the EK dev board. Datasheet should NOT indicate that NTC can be directly connected to GND and along with the schematic examples if charging is NOT working that way!

I assembled a second board and assembled the PMIC part. Its working as intended. So I conclude the problem lies only within the 1st board. 

Anyway I need to send this to fab again, can t fix the trace since its underneath. 

Thank you for helping me solve the issues Parth.
