Maxim Integrated MAX17058X+T10 Product Overview

The MAX17058X+T10 is a sophisticated, single-cell fuel-gauge IC from Maxim Integrated, designed to provide precise monitoring of lithium-ion (Li+) batteries in portable devices. This compact, power-efficient component is an ideal solution for a wide range of applications, including smartphones, tablets, wireless speakers, and other handheld electronics that require accurate battery state-of-charge (SOC) indications.

Key Features

• ModelGauge™ m3 Algorithm: The MAX17058X+T10 incorporates Maxim's proprietary ModelGauge m3 algorithm, which eliminates the need for battery characterization for most applications. This advanced algorithm provides a more accurate SOC by combining the short-term precision of a coulomb counter with the long-term stability of a voltage-based fuel gauge.
• Low Power Consumption: With an operating current of just 23µA, the device is optimized for power-sensitive applications, ensuring minimal impact on battery life.
• Easy Implementation: The IC simplifies design efforts with its no-trim-required operation and the ability to provide SOC data without the need for an external current-sense resistor, reducing both cost and space.
• High Accuracy: The MAX17058X+T10 offers high accuracy in SOC reporting, with an error of less than 1% under most operating conditions.
• Compact Form Factor: Available in a tiny, lead-free 10-pin TDFN package, this device is suitable for space-constrained applications.

Communication and Configurability

The device communicates with the host system via an I2C interface, allowing for easy integration into existing designs. It is also highly configurable, providing adjustable alert thresholds for SOC low and SOC high warnings, which can help extend battery life and safeguard against unexpected shutdowns.

Protection and Safety

With built-in protection features, the MAX17058X+T10 ensures safe operation across various conditions. It includes temperature compensation and automatic compensation for cell aging, ensuring reliable performance over the product's lifespan.

Conclusion

The Maxim Integrated MAX17058X+T10 is a sophisticated, low-power, and highly accurate fuel-gauge IC that provides critical battery information to enhance the user experience of portable devices. Its integration of the ModelGauge m3 algorithm and ease of use make it an excellent choice for designers looking to optimize battery performance and extend device run time.
