I have a battery-powered product for which I am developing firmware, and the HW design team have designed this with a BQ27410 fuel gauge. I am having some issues with getting everything to run properly and would appreciate help from TI and the community.
1: I am having tool issues. Currently I use an "EV2400" hardware to connect to the fuel gauge over I2C, and "Gauge Studio 1.4.1" as PC side software. Unfortunately this does not allow me to do calibration of the gauge, and also some operations are not reliable (programming of firmware, importing .dmi and .gg files, writing of data memory parameters, etc, fail more often than succeed). I have attempted to use "bq Evaluation Software 0.9.75" and it has similar issues, however it manages to write calibration data (the software reports that calibration failed, but the measured current after calibration matches the actual load current.).
What is the recommended tool combination from TI for working with this fuel gauge?
2: What is the correct procedure to setup the gauge to go through the power states "normal -> sleep -> hibernate"? The "sleep" bit in "operation configuration" register is set (to enable sleep), load current is below the sleep current and the MCU is writing the "set hibernate" command just before it itself shuts down. Still the gauge supply current stays around 100~110µA which is the "normal mode" current. Is there something clearly missing in this sequence?
I would appreciate any suggestions!
