The MAX17043X+ is a compact, low-cost, and highly integrated fuel gauge IC designed by Maxim Integrated for lithium-ion (Li+) batteries in handheld and portable technology. It is a perfect solution for real-time battery monitoring and provides critical data such as remaining battery charge, operational status, and battery health.

Key Features

• ModelGauge Technology: The MAX17043X+ incorporates Maxim's proprietary ModelGauge algorithm, which eliminates the need for battery characterization and simplifies the battery fuel gauging process. This technology provides a more accurate state-of-charge (SOC) estimation compared to traditional methods, even under varying load conditions and temperatures.
• Easy Integration: This IC is designed for seamless integration with a variety of microcontrollers, as it communicates via a standard I²C interface. Its small package size makes it an ideal choice for space-constrained applications.
• Low Power Consumption: With an operating current of only 23µA, the MAX17043X+ is optimized for power-sensitive applications, helping to extend the battery life of the end product.
• Configurable Alert Function: It features an adjustable alert threshold, which notifies the host processor when the battery falls below a specified level. This allows for proactive power management and can prevent unexpected device shutdowns.

Applications

• Smartphones and Tablets
• Portable Media Players
• Wireless Headsets and Earbuds
• Health and Fitness Monitors
• Other Battery-Powered Devices

The MAX17043X+ is available in a tiny, lead-free, 8-pin TDFN package, making it suitable for the latest portable electronics that demand minimal footprint and weight. Its robust design ensures reliable performance across a wide range of environmental conditions, making it a versatile choice for developers looking to enhance the user experience by providing accurate battery information.
