The MAX17047G+T10 is a compact, high-precision fuel gauge integrated circuit (IC) developed by Maxim Integrated, designed to provide accurate battery state-of-charge (SOC) information for single-cell lithium-ion (Li+) batteries. This sophisticated IC is an essential component for portable devices where battery life prediction is critical, such as smartphones, tablets, and wireless headphones.

Key Features

• ModelGauge™ Algorithm: The MAX17047G+T10 incorporates Maxim's proprietary ModelGauge algorithm which eliminates the need for battery characterization for most applications. This advanced algorithm provides automatic compensation for cell aging, temperature, and discharge rate, delivering more accurate SOC readings.
• Low Quiescent Current: With an ultra-low quiescent current of just 23µA, the MAX17047G+T10 helps to maximize the battery life of the host device, making it an energy-efficient choice for modern electronics.
• Easy Implementation: The fuel gauge does not require an external sense resistor and integrates smoothly with existing device architectures, simplifying the design and reducing time to market.
• I2C Interface: Communication with the host system is facilitated through an I2C interface, which allows for easy integration with most microcontrollers and processors.
• Configurable Alert Function: An alert function can be configured to notify the system when the battery reaches a user-defined threshold, enabling proactive power management.
