Battery protection low voltage disconnect issue
Battery protection low voltage disconnect issue
(OP)
Hello all,
just got my first EasyEDA project back from JCLPCB and it’s almost as I envisioned it.
My issue is the under voltage protection. It correctly disconnects the battery but I can still measure 0.7V between Vcc and GND.
My question: how to track down this issue?
I have attached the full circuit, the bottom part is the charger which was a public circuit I just integrated. It seems to be a standard implementation of the parts.
Thanks in advance,
Markus

what I can measure now is a is -0.2V (when the battery is completely removed) coming from the 25x WS2812 LEDs when they are exposed to light.

Is the circuit wrong? I have attached the 'typical application' diagram from the specs.

In- and output to the mosfet module was swapped
