DS2762BE+025/T+R – MAXIM INTEGRATED

The Maxim Integrated DS2762BE+025/T+R is a stand-alone, high-precision fuel gauge IC designed for single-cell lithium-ion (Li+) battery packs. It integrates a high-accuracy current accumulator, voltage measurement, and temperature sensing to provide precise state-of-charge (SOC) and state-of-health (SOH) estimations. The device outputs battery voltage and current data via a 1-Wire interface. The DS2762BE+025 variant features a voltage rating of 3.0V and a current rating of 25mA for its output. Encapsulated in a small 8-pin TSSOP SMD package, it optimizes board space. Its operating temperature range spans from -20°C to +70°C. Commonly used in portable devices, power tools, and backup power systems, the DS2762BE+025/T+R offers superior accuracy and simplified integration compared to discrete fuel gauging solutions, reducing component count and BOM cost. Its unique cell modeling algorithm allows for adaptive learning, improving SOC accuracy over the battery’s lifespan.
