Page 4: Introduction
NDA Confidential Introduction DA9070 Fuel Gauge EVK is a fuel gauge development and evaluation platform to demonstrate a low power fuel gauge system using the DA9070, DA9231, and an MCU with Dialog's proprietary algorithm. The DA9070 is an ultra-low quiescent current PMIC with integrated charger, buck converter, boost converter, and 3 LDOs. -

-System Load Model: A set of on-board resistors with ON/OFF control issued by MCU to mimic various load patterns in real applications -PC GUI: Software on PC. For chip evaluation. Both registers of DA9070 and DA9231 can be read or written through GUI -PC PPM: Software on PC. -
Page 7: Chip Evaluation Mode
NDA Confidential Chip Evaluation Mode DA9070 Fuel gauge EVK is able to be configured to perform chip evaluations with or without battery. For example, DA9070 or DA9231 can be evaluated for current consumption, efficiency, load/line regulation, load/line transient etc. without battery; DA9070 can also be evaluated for sequence, system load transient while the battery being plugged-in. -

DA9231 are OTP programmed to start up automatically as soon as the EVK board is powered. - If the USB cable is connected to a PC, open the "DA9070 Fuel Gauge EVK" GUI that was installed on the PC. Start to configure device registers as well as read device status using GUI, as shown in... -
Page 9: Da9070 Evaluation
The typical application diagram of DA9070 is shown in Figure 5. DA9070 includes a Buck regulator, a Boost Regulator, 3x LDO/LDSW, and a linear battery charger. On DA9070 Fuel gauge EVK, each regulator can be evaluated individually. It is recommended to... -

Descriptions +/ S+/ S-/ - + and - are terminals for connecting an external load to the DA9070 VDD_SYS; S+ and S- are kelvin (VDD_BUCK_M) sense points for DA9070 Buck input. For input voltage measurement during efficiency test, S+ and S- should connect to multi-meter for better accuracy. - Page 11 MODE LDO0_LD/ +/ - + and - are terminals for connecting an external load to DA9070 LDO0 output; When pin-1 is shorted to the (LDO0_LD) + pin on J18, the on-board load resistor will be used as the LDO0 output load.

VDDIO can be connected from 4 options by installing a jumper between VDDIO pin and the pin VLDO_SL/ VDDIO next to its left: DA9070 Buck, DA9231 Buck, DA9231 LDO, or independent 2.5V supply. VO_BUCK_M/ VDDIO For evaluation purposes, the 2.5V supply position is recommended to provide communications regardless of which IC is enabled. -
Page 16: Battery Profile Mode
(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. -

Board calibration can also be performed using the PPM software. The main PPM windows are shown in Figure 10. Figure 10: PPM windows Please refer to Application Note AN-SW-121 DA9070 Power Profile Manager and SOCF for step-by- step instructions on how to perform these tests. User Manual Revision 2.1... -
