Hi guys nice project! I think i got a counterfeit cj125 lot, can somebody make some resistance measurements between ub and gnd and between diahd and diahg (should be pin 6-7 of SOIC24)? I hope someone helps me!
Have you had your assembled at JLCPCB?
I have some done and the shunt diode they used was just a normal dual diode so it doesn't work correctly.
Nope, i had to integrate the bl49sp design on my board and i only changed the package to soic24. Found every component in lcsc but had to buy cj125 on aliexpress. I think they are sooo fake, some don't answer at all using spi and others are a straight short between ub and gnd. I know how to solder, i've done countless projects, and i am pretty sure my schematic is right. That's why i need help, i need to know what a good known chip is like
