Product Overview


DC1496B-B is an demonstration board for evaluation of LTC2942 ADC. It measures battery charge state, battery voltage and chip temperature in 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. Battery voltage and on chip temperature are measured with an internal 14bit no latency delta sigma ADC. The three measured quantities (charge, voltage and temperature) are stored in internal registers accessible via the on board SMBus/I2C interface. It features programmable high and low thresholds for all three measured quantities. If a programmed threshold is exceeded, the device communicates an alert signal. DC1496A may be connected directly to target application’s analog signals while using DC590 USB serial controller board and QuikEval System software to measure performance.
