BRCL4056BSE 产品概述

一、概述

BRCL4056BSE 是 BLUE ROCKET 推出的单节锂离子电池线性恒流/恒压充电控制 IC,专为单节 3.7V 锂电池充电设计。芯片工作在 VDD = 5V 环境下,支持 0V 电池预充、电池正负极反接保护和电池温度检测,静态电流极低,适合便携式、低功耗的电源管理场景。封装为 ESOP-8,便于 PCB 布局与散热处理。

二、主要参数

  • 最大充电电流:1.2 A(通过外接设定元件配置)
  • 工作电压(VDD):4V ~ 6V(典型 USB 5V 供电)
  • 充电终止电压:4.20 V(单节锂离子电池)
  • 支持 0V 电池充电(预充/涓流充电)
  • 电池温度检测:支持(NTC 温度探测接口)
  • 静态电流(Iq):3 μA(待机/停止状态极低耗电)
  • 工作环境温度:-40 ℃ ~ +85 ℃
  • 封装:ESOP-8
  • 保护功能:电池反接保护、过温限制、恒流/恒压充电策略

三、功能与工作流程

BRCL4056BSE 采用经典的恒流-恒压(CC/CV)线性充电算法:

  1. 预充(涓流):对深度放电至 0V 附近的电池先以小电流预充,确保电池电压回升到安全范围。
  2. 恒流快充:达到预设安全电压后进入恒流充电阶段,电流由外部设定,最大可达 1.2A。
  3. 恒压吸收:电池电压达到 4.20V 时转为恒压充电,电流逐渐下降至终止电流。
  4. 充电终止与维护:充电电流低于设定阈值或达到安全计时器/温度限制时终止;电池电压下降后自动开启补充充电。

此外芯片内部具备热关断与限流保护,防止线性耗散导致过温。

四、典型应用场景

  • 便携式设备(蓝牙耳机、MP3、便携感测终端)
  • USB 供电的移动电源管理与充电模块
  • 智能家居小型电池供电设备
  • 工业便携测量仪表与一次性/可充电替代设计

五、设计与工程注意事项

  • 散热:作为线性充电器,功耗主要为 (VDD - VBAT) × ICHG。高电流充电时需注意封装散热和 PCB 铜箔散热面积设计,以避免热降额。
  • 充电电流设置:通过外接电阻/程序端设定充电电流,推荐在 PCB 布局阶段预留可调元件以便调试。
  • 温度监测:建议连接电池组 NTC 至温度检测引脚,实现充电温度窗口管理(如标准 JEITA 策略)。
  • 输入保护:配合输入过压、反接保护与熔断器,提高系统可靠性。
  • 外围电容:在输入与电池端增加合适的去耦电容,抑制瞬态与提高稳定性。
  • EMC 与安规:为满足产品认证要求,应在设计中考虑 PCB 接地、滤波及屏蔽措施。

六、小结

BRCL4056BSE 是一款功能全面、静态功耗低、支持 0V 唤醒和电池温度检测的单节锂电池线性充电控制 IC。其 1.2A 的最大充电能力和 ESOP-8 封装使其在便携与中等功率应用中具有良好平衡。对于需要简洁外围、可靠恒流恒压充电并兼顾低待机功耗的系统,BRCL4056BSE 是一种值得考虑的解决方案。若需原理图建议或热设计指导,可根据具体应用电流与输入-电池电压差提供更详细的工程建议。

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
