The 4056H is an ESOP-8 battery management integrated circuit (IC) manufactured by Fuman. It is compliant with RoHS directives and is designed for battery over-discharge protection and accurate voltage, current, and temperature protection in applications such as mobile phones, electric vehicles, and UPS systems. It is equipped with comprehensive safety protection functions, including full protection against over-voltage, under-voltage, over-current, over-temperature, short circuit, and monitoring of reverse polarity protection. It also supports two alarms (high/low voltage, high/low current, and high temperature) of different thresholds for accurate system warning and protection. Its integrated voltage comparator provides better detection accuracy, and its low current consumption design provides improved system reliability.
