PRODUCTION DATA
The battery connection on the BAT pin is used for two purposes:
A capacitor of value of at least 1 µF should be connected between BAT and VSS. The capacitor should be placed close to the gauge IC and have short traces to both the BAT pin and VSS.
The fuel gauge has an integrated LDO with an output on the VDD pin of approximately 1.8 V. A capacitor of value at least 2.2 µF should be connected between the VDD pin and VSS. The capacitor should be placed close to the gauge IC and have short traces to both the VDD pin and VSS. This regulator must not be used to provide power for other devices in the system.
