Is normal this charging current on pin 16 ? Graph above is voltage on pin 16.

I expect a continuous current.

Found this in all prototypes (10 boards).

Vin voltage is about 4.5V

Battery seems to charge normally.

Hello Ronald,
I'm currently looking into this. I'll follow up when I have an answer.

Hello Ronald,

This may be due to the low input voltage. As shown below, V(IN_DPM) is typically 4.5V which is the minimum required to properly charge the battery. I would suggest increasing the input votage to 5V.
