Typical applicaTion
DescripTion
1A I2C Battery Gas Gauge
with Internal Sense Resistor
The LTC2941-1 measures battery charge state in battery-
powered 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. The measured
charge is stored in internal registers. An SMBus/I2C in-
terface accesses and configures the device.
The LTC2941-1 features programmable high and low
thresholds for accumulated charge. If a threshold is ex-
ceeded, the device communicates an alert using either the
SMBus alert protocol or by setting a flag in the internal
status register.
