BL8573CB6TR 产品概述

一、产品简介

BL8573CB6TR 是贝岭(BELLING)推出的一款面向单节锂电池充电管理的充电芯片,采用 SOT-23-6 小封装,适用于对体积和成本敏感的便携式产品。芯片设计针对单节锂离子/锂聚合物电池,提供高效、可靠的充电管理解决方案。

二、核心参数

  • 最大充电电流:1.5A(可配置/限制)
  • 工作电压范围:4.25V ~ 6V(供电/输入范围)
  • 充电终止电压(饱和电压):4.20V(对单节锂电池)
  • 静态电流(Iq):25µA(待机低功耗)
  • 电池类型:单节锂电池(1S)
  • 工作温度:-40℃ ~ +85℃
  • 封装形式:SOT-23-6

三、主要特性与功能

BL8573CB6TR 在核心参数上满足单节锂电池的常见充电需求,具有以下典型优势:

  • 适合 USB 或小型适配器供电的输入电压范围;
  • 最大 1.5A 的充电能力,能够满足智能手持设备、便携电源等中等功率充电需求;
  • 低静态电流(25µA),有利于系统在无充电时降低待机耗电;
  • 封装小、热阻可控,便于 PCB 布局和批量生产。

(注:具体内部充电算法如恒流恒压、充电终止逻辑、热保护或状态指示等,请参考官方数据手册以确认实现方式与参数。)

四、封装与引脚说明

SOT-23-6 小封装便于空间受限应用。典型引脚功能包含:电源输入(IN)、电池输出/充电电流路径(OUT或BAT)、地(GND)、充电电流设定(PROG)、状态指示(STAT)及温度监测/使能(NTC/EN)等。实际引脚配置请严格以厂家原厂版脚位定义为准。

五、典型应用场景

  • 便携式消费电子:蓝牙耳机、小型音响、手持设备;
  • 便携电源与移动充电宝(小容量);
  • 工业与物联网终端:数据采集器、传感器节点、便携式检测仪器等;
  • 其他对单节锂电池充电管理有体积与成本要求的场景。

六、设计建议与注意事项

  • 输入与电池端需配置推荐电容以保证稳压与环路稳定;高充电电流下注意 PCB 铜箔散热,必要时做散热铺铜;
  • 根据实际充电电流需求,按数据手册设置编程电阻或外部限流元件,避免长期高温工作导致热降额;
  • 使用前查阅并遵循贝岭官方数据手册中关于电气极限、热特性、外部器件选型与推荐布局的具体要求;
  • 关注充电安全(温度监测、短路保护、过流/过压保护等),在系统层面增加必要保护措施以提高可靠性。

总结:BL8573CB6TR 以其小封装、低静态电流与最高 1.5A 的充电能力,适合多种单节锂电池便携应用。为获得最佳性能与可靠性,请结合官方数据手册进行电路设计与布局验证。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
