Typical applicaTion
DescripTion
1A Battery Gas Gauge with
Internal Sense Resistor and
Temperature/Voltage
Measurement
The LTC2942-1 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
Σ
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 pro-
grammedthresholdisexceeded,thedevicecommunicates
an alert using either the SMBus alert protocol or by setting
a flag in the internal status register.
