BL8573CS8TR 产品概述
BL8573CS8TR 是贝岭（BELLING）推出的一款单节锂电池充电管理芯片，封装为 ESOP-8，面向便携和低功耗应用场景。芯片集成常见充电管理功能，适配 1 节锂离子/锂聚合物电池，为系统提供稳定、安全的充电解决方案。
一、主要规格
- 芯片类型：充电芯片（电池管理）
- 工作电压（输入）：4.25 V ～ 6.0 V
- 最大充电电流：1.5 A
- 充电饱和电压（浮充电压）：4.20 V
- 电池类型与节数：锂电池，1 节
- 工作温度范围：-40 ℃ ～ +85 ℃
- 电池温度检测：不支持外置温度检测功能
- 静态电流（Iq）：25 μA
- 封装：ESOP-8
- 品牌 / 型号：BELLING / BL8573CS8TR
二、功能特性
- 恒流（CC）/ 恒压（CV）充电流程，支持标准锂电池充电曲线。
- 可编程充电电流，通过外部元件调整输出电流（设计时应限制在最大 1.5 A）。
- 软启动（Soft-start），启动时限制输入冲击电流，降低对电源的瞬态影响。
- 欠压锁定（UVLO），保证在输入电压不足时芯片进入保护态，避免异常工作。
- 涓流充电（Trickle）与自动再充电（Auto-recharge），对深度放电电池进行安全预充并在放电后自动恢复充电。
- 充电终止功能，电池接近饱和时停止充电以防过充。
- 低静态电流，适合对待机功耗敏感的便携设备。
三、典型应用场景
- 移动电源、便携式消费电子（蓝牙设备、耳机、手持终端）
- 智能家居与物联网终端（需要长待机与周期充电的节点）
- 小型医疗设备与备电系统（单节锂电池供电的场合）
四、设计与使用注意事项
- 输入电源应稳定并能提供充电电流峰值，典型输入为 USB 5 V 或相应电源。
- 充电电流需通过外部电阻或设计参数编程，严禁超过 1.5 A。
- 芯片不具备电池温度检测功能，若产品有严格温度要求，应外加热敏元件或在系统层面做温度管理与保护。
- 布局上应注意电源回路的散热与铜箔面积，ESOP-8 封装在高电流工作时需保证良好散热路径。
- 系统需配合合适的保护电路（电池保护板、过流/过压/短路保护）以提高整机安全性。
五、封装与可靠性
- ESOP-8 封装利于表面贴装与批量生产，适合空间受限的便携设备。
- 工作温度覆盖-40 ℃ 至 +85 ℃，适合大多数室内和一般户外环境，但在极端高温环境需做额外散热或限制充电策略。
六、总结
BL8573CS8TR 是一款功能完备、低静态电流的单节锂电池充电管理芯片，提供恒流恒压、涓流、软启动、欠压锁定与自动再充电等关键功能。其最大 1.5 A 的充电能力及 4.2 V 的饱和电压规格，使其在便携消费电子和低功耗 IoT 设备中具有较高的适用性。设计时需注意外部编程方式、散热与温度保护，以确保长期可靠运行。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
