DA9070 / DA9231 Fuel Gauge Development Kit
Battery Profile Mode
The DA9070 Fuel gauge EVK board can also be configured to perform battery characterization
(battery profile) and run a fuel gauge performance test. This is done using the Power Profile Manager
(PPM) software instead of the DA9070 Fuel Gauge GUI. The profile data for a specific battery is
generated by the PPM and loaded to the MCU. This profile is then used by the pre-loaded Dialog
algorithm for the SOC fuel gauge.
If the included 80mAh battery is used, battery profiling is not necessary; the MCU is pre-loaded with
both the fuel gauge algorithm and 80mAh battery profile.
Also pre-loaded to the MCU is the eval board calibration data. The calibration steps are described in
AN-SW-121 but do not need to be performed in most cases.
Figure 9
shows the jumper set-up of the DA9070 Fuel gauge board while battery profiling is running.
Note the jumper position of J14 in battery profile mode.
