Product details

Single-cell fuel gauge with integrated fault protection

The MAX17303X+T is a ModelGauge™ fuel gauge IC from Analog Devices, purpose-built for single-cell Lithium-Ion and Lithium-Polymer battery packs. It communicates over an I²C bus and integrates fault protection against overcurrent, overtemperature, overvoltage, and short-circuit conditions — covering the main failure modes a battery management system needs to guard against.

Package and temperature grade

Housed in a 15-WLP (Wafer-Level Package) measuring 1.68 x 2.45 mm, the MAX17303X+T is a surface-mount device that suits space-constrained portable designs.

Frequently asked questions
