Analog Devices Inc. LTC2943多單元電池氣量計

Linear Technology/Analog Devices LTC2943 Multicell Battery Gas Gauges can be used to measure battery charge state, voltage, current and temperature in portable product applications. The LTC2943 has a wide input voltage range that allows use with multicell batteries up to 20V. A precision coulomb counter integrates current through a sense resistor between the battery's positive terminal and the load or charger. Voltage, current, and temperature are measured with an internal 14-bit No Latency ΔΣ™ ADC. The measurements are stored in internal registers accessible via the onboard I²C/SMBus Interface.
