MAX17055ETB+T 产品概述

一、产品简介

MAX17055ETB+T 是 ADI/Linear(原 Maxim)推出的一款单节电池监测芯片,集成 ModelGauge m5 EZ 算法,专为单节锂电池和磷酸铁锂(LiFePO4)系统提供高精度的荷电状态(SOC)估算与电池管理功能。工作电压范围为 2.3V 至 4.9V,静态电流仅 7 µA,适合对待机功耗敏感的便携与工业应用。

二、主要特性

  • 单节电池专用:支持 1 节锂电池与磷酸铁锂电池化学体系。
  • 精准 SOC:内置 ModelGauge m5 EZ 算法,减少系统标定工作,提升容量与剩余电量估算准确度。
  • 宽工作电压:2.3V ~ 4.9V,覆盖常见单节电池电压范围。
  • 放电截止参考:常用放电截止点可设为 3.3V,适配 LiFePO4 典型截止电压。
  • 低功耗:静态电流(Iq)约 7 µA,适合长续航设备。
  • 大电流支持:适用于高达 7 A 级别的充放电场景(系统需配合适当电流采样与保护设计)。
  • 温度监测:支持电池温度检测,便于热管理与安全控制。
  • 通信接口:I2C 总线接口(兼容常见主控),便于与 MCU 集成。
  • 工业级温度:工作温度范围 -40℃ ~ +85℃。
  • 封装:TDFN-10-EP,带散热墩,型号末尾 +T 表示卷带包装(Tape & Reel)。

三、典型应用场景

适用于对电池剩余电量估算要求高且需低静态功耗的场合,例如便携式设备、工业单节供电模块、智能测量终端、可穿戴设备、移动电源及其他需精确电量管理的单节锂电系统。

四、接口与封装说明

芯片通过 I2C 接口与主控通信,支持常见读写寄存器访问 SOC、剩余容量、健康状态、温度与电流等数据。TDFN-10-EP 封装利于 PCB 布局与热量散发,+T 卷带包装便于量产贴片工艺。

五、设计注意要点

  • 电流检测:推荐使用低温漂精密采样电阻(Shunt),并合理布线以降低误差。芯片测量范围与系统电流规格需匹配。
  • 温度测量:电池温度传感元件应靠近电池主体放置,以反映真实电池温度;芯片自身温漂和补偿参数需要在系统级验证。
  • I2C 布线:在长线或多设备场景下注意上拉电阻选择和总线抗干扰设计,必要时加滤波与隔离。
  • 放电截止与化学适配:对于 LiFePO4 与普通锂电池,请根据化学特性设置不同截止电压与保护参数(示例放电截止 3.3V 可作为 LiFePO4 参考)。
  • 固件集成:利用 ModelGauge m5 EZ 提供的寄存器与算法参数,结合系统使用场景进行初始配置即可获得较高准确度,常规建议在量产前进行样机验证。

六、优势与实施建议

MAX17055ETB+T 将高精度的 SOC 算法与低功耗、工业级温度支持结合,适合对电池管理要求严格且希望缩短开发周期的项目。建议在设计初期确认电流范围、采样电阻规格与温度传感布置,并在整机环境下做能量计量与边界条件测试,以确保算法输出与系统期望一致。

七、型号与采购信息

  • 型号完整示例:MAX17055ETB+T(TDFN-10-EP,带卷带包装)
  • 品牌:ADI / LINEAR(Maxim 系列)
  • 在采购与生产时请确认封装、批次与工业温度等级,并参考厂商数据手册获得详细引脚定义与应用电路。

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
