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.
