The LTC2943-1 measures battery charge state, battery voltage, battery current and its own temperature in portable product applications. The wide input voltage range 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.
The LTC2943-1 features programmable high and low thresholds for all four measured quantities. If a programmed threshold is exceeded, the device communicates an alert using either the SMBus alert protocol or by setting a flag in the internal status register.
