MAX17320G10+

Overview

The MAX17320G10+ is a battery fuel gauge IC designed for 2 to 4 series lithium-ion or polymer cells. It features ultra-low quiescent current of 38µA and integrates ModelGauge m5 EZ algorithm for accurate state-of-charge estimation. The device includes built-in protection against over-current, over-temperature, and over/under-voltage conditions. It supports optional SHA-256 authentication and detects internal self-discharge. Packaged in a 24-TQFN (4x4mm) exposed pad, it enables reliable power management in compact designs.
