Hello,
I use the BQ20Z65-R1 in a new design. This design is similar to the evaluation board bq20z65EVM. The main différences are the MOSFET ref, and the sense resistor value (see the attached schematic gas gauge.pdf).
I have configured the register 0x71 at 0x7D0 (because Rsense = 2mohm). The CfgA register is at 0x0E29 because only 3 cells are used.
3 resistors of 470 ohm are placed between each cell input instead of cells. A 12V voltage is applied between 3P and 1N
Here is a screeenshot of the registers:
All seems to be good, but the voltage on the pin DSG is 0V so the VBAT is 0V too.
Do you have any idea why the output is not working ?
