BQ40Z50-R1: developing a gauge for a lipo 4s battery

Part Number: BQ40Z50-R1

Hello everyone,

I am currently developing a gauge for a lipo 4s battery. I chose to add mosfet in extren in order to unload more quickly the cells.

The problem that I meet and that I can not find the pine entrenched in red. That connect at least cell 1 and resistor Rs.

I resumed the information of the datasheet  SLUA420A.

Another small question the WAKE (S1)  switch for what use exactly

Best regards anthony
