BQ40Z80: Pin configuration Issues (Pin 15)
Part Number: BQ40Z80
I have any the same things after Reseting the gauge
Batt is out of office. Can you be a little bit more descriptive about the issues you are facing?

I try to managed GPIO Pin.
I have right configured Data Memory for activating Pin 12 and Pin 15.
Now I have good for Pin 12 but not for Pin 15, it is always ON.
Data Memory configuration :
1- Setting/Configuration/Pin configuration = 0x 0183
2- Setting/Configuration/FlagMapSetUp0 = 0x8841
3- Setting/Configuration/FlagMapSetUp0 = 0x8041
A - When FD flag of Battery Status are Set OFF (Green) then :
-> Pin 12 is set to 0 V
-> Pin 15 is set to 1.51 V
B - When FD flag of Battery Status are Set ON (Red) then :
-> Pin 12 is set to 1.8 V
-> Pin 15 is set to 1.51 V instead of 1.8V
Can you try this ?

Can you provide a gg.csv file for us to review and test?

Work In progress!
I have 2 issues :
1- I'm using GPIO the Pin 15 for enable a LDO regulator (TPS70930DBVR : Texas Instrument). Without this composant I haven't 1.51 V. So my first issue are a flowing current through EN input to IN input from LDO regulator. I will use a stage with Mosfet between the BQ and LDO regulator for solve It.
2- Without LDO regulator, when I write Word 0x100 on command 0x49 (GPIOWrite()), I have right 0x11 on 0x48 read (GPIORead()) and GPIO pin 15 are good 5V (3.5 V with small load) . With reverse command I have good 0 V on the GPIO Pin 15.
=> But the signal keep always to 0 V with FlaMapSetUp function !

Please find a gg.csv file attached,
Can you attach the schematic?
