DESCRIPTION
The LTC ? 2941 measures battery charge state in battery-
supplied 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 a sense resistor between the battery’s positive
terminal and the load or charger. The measured charge
is stored in internal registers. An SMBus/I 2 C interface
accesses and configures the device.
The LTC2941 features programmable high and low thresh-
olds for accumulated charge. If a threshold is exceeded, the
device communicates an alert using either the SMBus alert
protocol or by setting a flag in the internal status register.
The LTC2941 requires only a single low value external
sense resistor to set the current range.
