The LTC2941 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/I2C interface accesses and configures the device.
The LTC2941 features programmable high and low thresholds 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.
