I have a bq34z100 chip in an original board design and am experiencing issues with the gas gauge mode. The chip calibrates correctly for voltage and temperature, but gives me an error when I try to push current through the sense resistor to calibrate I get the following error: "Error setting to GG Mode."
In addition, the RAM data displays a high "resting" current of over 100 mA even when no load is applied. When a load is applied the current increases a little but stays around 100-200 mA, instead of the 1.5 A my load draws. This board design has worked in the past, and the chip correctly reads voltage and temperature, LEDs light up correctly, etc. so it seems to be some problem or setting with the chip. I'm wondering if the chip is bad and needs to be replaced or if I need to try changing some of the chip's settings.
Below are some screen shots.
