概述

Description

MAX17050X+T10 is Maxim Integrated’s (now Analog Devices) digital Li‑ion battery fuel gauge family. It continuously estimates state of charge (SOC), remaining capacity, and time‑to‑empty for single‑cell packs. It uses Maxim’s ModelGauge algorithm to give accurate SOC with minimal calibration, by sensing pack voltage, current (via an external sense resistor) and temperature, and storing data in nonvolatile memory. It interfaces with a host MCU over I2C (SMBus in some variants) and requires only a few external components. The T10 suffix denotes a compact 10‑pin package option suitable for mobile devices. Common applications include smartphones, wearables, tablets, and other battery‑powered products needing reliable SOC without complex external computation. Benefits include high accuracy, low quiescent current, easy integration, and reduced BOM.

Features

Key features of MAX17050X+T10 (fuel gauge for single-cell Li-Ion/Li-Po):
- ModelGauge-based SOC estimation for Li-ion cells without extensive battery characterization.
- I2C/SMBus digital interface for reading SOC, voltage, current, temperature, remaining capacity (mAh), and runtime estimates.
- Measures pack voltage, current (via sense resistor), and temperature; reports health/status indicators.
- Automatic capacity learning with aging compensation to adapt to battery changes over time.
- Low-power operation with sleep modes and configurable interrupt/alert outputs for thresholds.
- Small footprint package options (8-pin/compact packages) suitable for space-constrained designs.
- Robust operating range with wide temperature support and fast startup for responsive gauging.
- Simple implementation with minimal external calibration and no extensive characterization required.

Package

It uses a 10-pin TDFN package (TDFN-10, 3×3 mm).

Pinout

- Pin count: 10 pins (T10 package).
- Function: Li‑ion battery fuel gauge IC (coulomb counter with SOC/remaining capacity estimation) using an I2C‑compatible interface for status reporting (voltage, current, SOC).
