DC1496B-A demonstration circuit features the LTC2941 battery gas gauge. It 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 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 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. The DC1496B is a part of the QuikEval system for quick evaluation with a host controller through a PC.
