R5460N208AA-TR-FE — 2串锂电池保护IC(NISSHINBO,SOT-23-6)

一、产品概述

R5460N208AA-TR-FE 是日清纺(NISSHINBO)面向两节串联锂离子/聚合物电池组的电池保护芯片,封装为紧凑型 SOT-23-6。该器件工作电压范围为 1.5V 至 10V,适配 2S 电池组(名义 7.4V)使用场景,工作温度范围 -40℃ 至 +85℃,适合消费类与便携设备中对体积、成本和可靠性有较高要求的场合。

R5460N208AA-TR-FE 提供对过充、过放、过流/短路等典型故障模式的保护功能,通过内部逻辑和外部功率 MOSFET 的联动实现对电池的自动断开与恢复,保障电池与整机安全。

二、主要特性

  • 适配电池:锂离子(Li-ion)/聚合物(Li-Po),2 节串联组(2S)
  • 工作电压:1.5V ~ 10V(适用于整个电池包电压范围)
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOT-23-6,体积小,便于空间受限设计
  • 典型保护功能:过充保护、过放保护、充放电过流(短路)保护、延时/自动恢复逻辑
  • 适用于多种便携式电源应用,兼顾成本与可靠性

三、功能说明

R5460N208AA-TR-FE 的核心功能围绕电池安全管理展开,通常包括以下模块(具体实现和阈值请以厂商数据手册为准):

  • 过充保护(Overcharge):当电池组电压超过设定阈值时,芯片能够闭合控制端,切断充电路径,避免单体电池过压,保护电池寿命与安全。
  • 过放保护(Over-discharge):当电池组电压低于设定阈值时,芯片切断放电路径,防止深度放电引起容量衰减或电池损坏。
  • 过流/短路保护(Overcurrent/Short-circuit):在放电电流超过安全值或出现短路时,芯片通过检测电阻或电流信号,快速断开输出以限制电流并保护器件与电池。
  • 自动恢复与手动复位:在故障消除后,保护器件能够根据预定逻辑自动恢复工作;有些应用也可通过外部操作实现手动复位。
  • 低功耗待机:为延长电池待机时间,器件通常在正常待机状态下维持较低静态电流(具体数值请参考数据手册)。

四、典型应用场景

  • 便携式电子设备(掌上设备、便携式音响、手持终端)
  • 可穿戴设备与智能配件(体积受限、对保护要求高)
  • 小型电动工具与充电电源
  • 移动医疗设备、监测仪器等对工作温度范围与可靠性有要求的场合

五、封装与机械信息

  • 封装形式:SOT-23-6(小体积、便于自动贴装)
  • 尺寸优势:适合 PCB 面积受限的设计,可在多层板上靠近电池连接点布局,以改善检测与保护精度
  • 引脚功能与具体封装图请参照官方器件封装与管脚图;在 PCB 布局时建议将电流感测路径、功率 MOSFET 及旁路电容布局紧凑且短路线,降低寄生阻抗与噪声影响。

六、设计要点与注意事项

  • 查阅数据手册:尽管上文列出主要功能与参数范围,具体保护阈值、延时设定、复位条件以及内部时序需以 NISSHINBO 官方数据手册为准。
  • 晶体管与分流电阻匹配:若器件需配合外部 MOSFET,选型要匹配电流能力和 Rds(on);电流检测元件(如分流电阻)要按照预期的过流阈值选型并保证热稳定性。
  • PCB 走线与热管理:关键电流走线尽量短而粗,分流电阻与功率器件采用良好散热设计,避免局部热点。
  • 电磁兼容与滤波:在可能存在较大开关干扰的系统中,考虑输入/输出滤波和布局屏蔽,防止误触发。
  • 工作环境考量:器件支持 -40℃ 至 +85℃ 的工作温度,但在极端工况(高温长期运行或强振动)下应评估系统级可靠性。

七、配套与替代建议

在选择电池保护解决方案时,可同时参考同类 2S 保护 IC 的参数(工作电压、静态电流、保护阈值、封装与成本等),并根据最终产品的放电电流、尺寸和认证要求做权衡。若需要更强的均衡功能或更复杂的电池管理,则可考虑带有平衡或通信功能的 BMS 芯片或模块。

结语:R5460N208AA-TR-FE 以其针对 2S 锂电组的完整保护功能、宽电压与温度适应性以及 SOT-23-6 的小体积封装,适合用于对成本、体积与基本安全性有严格要求的便携式设备。在设计使用前,请务必详细阅读生产厂家的数据手册与推荐的参考电路,按规范进行 PCB 布局与热流管理,以确保系统的长期稳定与安全。

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.
