The MAX17058G+ from Maxim Integrated is a sophisticated battery fuel gauge integrated circuit (IC) designed to provide precise monitoring of single-cell lithium-ion (Li+) batteries. This compact, power-efficient component is an essential tool for portable device manufacturers who need accurate battery state-of-charge (SOC) indications to enhance user experience and to manage power effectively.

Key Features

• ModelGauge™ Technology: The MAX17058G+ incorporates Maxim's proprietary ModelGauge algorithm, which eliminates the need for battery characterization for most applications. This technology provides a robust fuel gauging solution by combining the virtues of both coulomb counting and voltage-based fuel gauging.
• High Accuracy: It offers high accuracy in SOC reporting with as little as ±1% error under various conditions, including temperature changes and battery aging.
• Low Quiescent Current: With an operating current of just 23µA, and a low-power 3µA hibernate mode, the MAX17058G+ helps to extend the battery life of portable devices.
• Configurable Alert Function: The device features an alert function that can be programmed to notify the system when the battery falls below a specified threshold, allowing for proactive power management.

Applications

• Smartphones and Tablets
• Portable Media Players
• Handheld Gaming Devices
• Wireless Headsets and Earbuds
• Health and Fitness Monitors

Easy Integration

The MAX17058G+ is offered in a tiny, lead-free 8-pin TDFN package with a footprint of just 2mm x 2mm, making it ideal for space-constrained applications. It interfaces with the host system via an I2C serial interface, allowing for easy integration into existing designs. Its operating temperature range from -40°C to +85°C ensures reliable performance across a wide range of environmental conditions.

Environmental and Quality Standards

Maxim Integrated is committed to environmental stewardship and quality. The MAX17058G+ is fully RoHS compliant and is produced in facilities that are certified to ISO 9001 quality management standards, ensuring both the sustainability and reliability of the product.
