Description
General part information
LTC2941-1 Series
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 interface accesses and configures the device.The LTC2941-1 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.Integrated Sense ResistorLTC2941NoLTC2941-1YesApplicationsLow Power Handheld ProductsCellular PhonesMP3 PlayerCamerasGPS
