The Maxim Integrated DS2786G+TR is a stand-alone, single-cell, fuel-gauge IC specifically designed for lithium-ion (Li+) and lithium polymer (Li-Poly) battery packs. It accurately monitors battery voltage, current, and temperature to estimate remaining capacity and battery health. The device employs a sophisticated algorithm to compensate for cell aging, temperature variations, and discharge rate. The DS2786G+TR features a 3.0V OUTPUT Voltage Rating and a 50mA OUTPUT Current Rating for driving external circuits or LEDs. Its small 14-pin TSSOP SMD Package Type makes it suitable for space-constrained applications. It operates within an Operating Temperature Range of -20°C to +70°C. The device is commonly used in portable devices such as smartphones, tablets, and wearable electronics, providing accurate battery status information and extending battery runtime by optimizing discharge profiles. Its key advantage lies in its high accuracy and low power consumption, enabling precise fuel gauging with minimal impact on battery life.
