R5460N208AF-TR-FE 产品概述

一、产品简介

R5460N208AF-TR-FE 是 NISSHINBO 面向 2 节锂离子/聚合物电池组的电池保护芯片(2‑Cell Li‑ion Battery Protection)。该器件采用 SOT-23-6 封装,工作电压范围宽(1.5V~10V),支持 0V 电池充电,适合对体积和功耗敏感的便携式与工业应用。芯片静态电流仅 100nA,有利于长待机寿命和低漏电设计。

二、主要规格(核心参数)

  • 型号:R5460N208AF-TR-FE
  • 品牌:NISSHINBO
  • 芯片类型:保护芯片(2 节电池)
  • 工作电压:1.5V ~ 10V
  • 支持电池:锂离子 / 锂聚合物
  • 电池节数:2 节(串联)
  • 0V 电池充电:支持(0V wake-up)
  • 静态电流(Iq):约 100 nA(超低待机电流)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SOT-23-6

三、关键功能与优势

  • 基本保护:针对 2 节锂电常见的过充、过放、过流/短路保护提供完整解决方案(典型保护逻辑需以数据手册为准)。
  • 0V 充电支持:允许完全放电后通过充电器唤醒电池并恢复保护状态,有利于电池复苏与维修场景。
  • 超低静态电流:100nA 级静态电流显著降低电池自放电带来的容量损耗,适合需要长时间待机的设备。
  • 宽电压适应性:1.5V~10V 的输入范围覆盖 2 节锂电的全工况(包括充电峰值),同时兼容低电压唤醒场景。
  • 小尺寸封装:SOT-23-6 便于在空间受限的移动设备与便携终端中布局。

四、典型应用场景

  • 小型移动电源、便携充电宝(2S 配置)
  • 手持设备、便携式音频与摄像设备
  • 工业便携终端、无线传感器和 IoT 节点(需长待机)
  • 医疗便携设备与应急电源系统

五、设计与使用建议

  • 与外部 N‑MOS/P‑MOS 保护 FET 配合使用时,注意 MOSFET 的 RDS(on)、耐压与布板布局,确保电流检测与热量管理可靠。
  • 在电路板布局上,将电流检测电阻和 GND 回流路径尽量靠近芯片引脚,减少寄生电阻/电感对检测精度的影响。
  • 0V 充电功能在不同充电器/系统下可能表现不同,设计时务必验证充电器兼容性与恢复阈值。
  • 工作温度范围为 -40 ℃ 至 +85 ℃,在极端温度条件下需考虑电池性能与保护阈值漂移。
  • 详细阈值、电流限值、时序和引脚定义请以官方数据手册为准,进行可靠性与安全性验证。

六、选型提示

若方案侧重超低待机电流、支持 0V 唤醒并要求小封装与 2S 锂电保护,R5460N208AF-TR-FE 是一个高性价比的选择。最终选型前,建议获取并核对完整数据手册和典型应用电路,结合目标负载电流、开路/短路保护需求与 PCB 空间做综合评估。

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
