Hi!
I'm reading the datasheet of the FS312F-G right now and in the "Typical Application Circuit" your R7 connects the CS-Pin with Bat- through 1k. But you use a 2k Resistor to connect the CS-Pin with common ground. Why is that?
Many Greetings!

My mistake! I got confused reading the datasheet.
Nice share. Thanks for the datasheet.

Is this for Lipo or for li-ion?
@pnarsai.interlog It is for Li-Po and Li-ion, since they got similar nominal voltage.
I think this PCB is for power bank circuit with over charge and over current protection. ( TP5086 IC module)
I've been having issues with a slightly modified version of this and am trying to figure out why.
Question #1: Why is Batt- not common with GND?
Question #2: The TP4056 recommends a 10uF capacitor between BAT and GND, but I do not see that anywhere. (Only a 0.1uf near the FS312F-G). Could this be the cause of some instability or extreme sensitivity to trace length/width?
