A 9-WFBGA, CSPBGA package would be appropriate for this. IC POWER SUPPLY SUPPORT CIRCUIT is the system battery's analog IC. The available channels are 1. Cut Tape (CT) cases are used for packaging. Surface Mount is positioned in the way of this electronic part. It can provide functions of type Battery Monitor. For the electronic part to perform properly, it should be operated at temperature -40°C~85°C TA. It is recommended that this battery protection IC be set to 3.6V at all times. The model is based on the STC3117 family. A voltage of 4.5V is reached when the maximum supply voltage (Vsup) is reached. A voltage greater than 2.7V (Vsup) must be required for a power supply. The power IC's series corresponds to OptimGauge™.
