MAX17048G+T10 产品概述

一、产品简介

MAX17048G+T10 是 ADI/Linear 系列面向单节锂电池的智能电量计(Fuel Gauge),基于 ModelGauge 智能算法,用于对电池剩余电量进行准确估算与管理。器件封装为 DFN-8-EP (2×2) 小尺寸封装,适合空间受限的便携与嵌入式系统。

二、主要技术参数

  • 工作电压:2.5 V ~ 4.5 V
  • 适配电池类型:锂离子/锂聚合物(单节为主)
  • 电池节数:1(器件系列亦面向 1-Cell/2-Cell 应用的家族设定)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 电池温度检测:不支持(需外接热敏元件时由主控读取)
  • 0V 电池充电:不支持(需外部充电管理或保护电路)
  • 静态电流 (Iq):约 3 µA(适合低功耗待机场景)
  • 通信接口:I2C(标准寄存器读写)

三、关键特性与优势

  • ModelGauge 算法:提供对电池状态(SOC、剩余容量等)的高精度估算,能够适应不同放电曲线与使用工况。
  • 低静态功耗:3 µA 静态电流有助于延长待机时电池寿命,适合对功耗敏感的物联网与便携设备。
  • 小型封装:DFN-8-EP (2×2) 便于空间受限的 PCB 布局与热管理。
  • 标准 I2C 接口:便于与 MCU、PMIC 或系统管理芯片集成,实现数据读取与参数配置。

四、典型应用场景

  • 手持设备与可穿戴终端
  • 物联网传感器节点、无线模块
  • 小型便携式医疗设备与健康监测器
  • 电池供电的工业控制与仪器

五、设计建议与注意事项

  • 供电与电压范围:确保器件工作电压维持在 2.5–4.5 V 范围;对单节锂电池,实现准确测量应考虑器件供电与电池端的隔离与滤波。
  • 温度测量:器件不支持内置电池温度检测,如需温度补偿应在系统中外接 NTC/热敏电阻并由 MCU 采样参与算法修正。
  • 0V 电池保护:器件不支持 0V 唤醒充电,需在系统中配置前级保护与专用充电管理 IC,以安全处理深度放电电池。
  • I2C 总线设计:增加必要的上拉电阻与滤波,注意多从机冲突与地址设定;在长线或噪声环境下考虑隔离或缓冲。
  • PCB 布局:为 DFN-8-EP 留出良好散热焊盘,靠近器件放置去耦电容,缩短 I2C 与参考信号走线长度以降低干扰。
  • 校准与学习:依赖 ModelGauge 的学习与校准过程,建议在产品开发阶段通过典型放电曲线完成初始标定,以获得更精确的 SOC 输出。

总结:MAX17048G+T10 以低功耗、智能电量估算与紧凑封装为特点,适合对续航与空间有较高要求的单节锂电池应用,但系统设计中需补充温度测量与深度放电保护等外围功能以保证整机性能与安全。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
