LTC2942-1 1A Battery Gas Gauge with Internal Sense Resistor and Temperature/Voltage Measurement DescripTion
The LTC®2942-1 measures battery charge state, battery voltage and chip temperature in handheld PC and portable product applications.

Its operating range is perfectly suited for single cell Li-Ion batteries. A precision coulomb counter integrates current through an internal sense resistor between the battery's positive terminal and the load or charger. Battery voltage and on-chip temperature are measured with an internal 14-bit No Latency TM ADC. The three measured quantities (charge, voltage and temperature) are stored in internal registers accessible via the onboard SMBus/I2C interface. The LTC2942-1 features programmable high and low thresholds for all three 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.
