SGM40560-4.2XTDI6G/TR 产品概述

一、型号与用途概述

SGM40560-4.2XTDI6G/TR 是圣邦微(SGMICRO)面向单节锂离子/锂聚合物电池充电管理的线性充电器方案(TDFN-6-AL 2×2 封装)。器件工作电压范围宽(2.7V ~ 7.5V),最大可设定充电电流为 700mA,采用典型的恒流-恒压(CC/CV)充电策略,充电饱和电压为 4.2V。该器件适用于便携式设备、低功耗智能终端及单节锂电池供电的各种电子模块的电源管理。

二、主要规格参数

  • 工作输入电压:2.7V ~ 7.5V
  • 最大充电电流:700mA(器件标称最大值,实际应用应参考 PCB 热与输入电源能力)
  • 充电饱和电压(终止电压):4.2V(适配标准单节锂离子/锂聚合物电池)
  • 支持电池节数:1 节
  • 工作温度范围:-40℃ ~ +125℃
  • 封装形式:TDFN-6-AL(2×2mm)
  • 品牌:SGMICRO(圣邦微)
  • 物料号后缀说明:TR 通常表示卷带包装(Tape & Reel),适合自动贴装生产

以上参数为器件的关键标称值,实际系统设计应结合数据手册中的典型电气特性和限制条件进行。

三、功能与典型特性

基于该型号的定位与常见线性锂电充电器设计,SGM40560-4.2XTDI6G/TR 常具备以下特性(具体功能以软件数据手册为准):

  • 恒流-恒压(CC/CV)充电曲线,自动从恒流过渡到恒压阶段直至电池接近饱和;
  • 4.2V 终止电压精度控制,保证电池安全充满;
  • 充电电流可配置/外置电阻设定(通常通过外接电阻设定最大充电电流);
  • 过温保护与热调节(当器件或 PCB 温度升高时自动降低充电电流以保护器件);
  • 输入欠压/过压保护与短路保护(常见于成熟充电管理器件中);
  • 小尺寸封装,适用于空间受限的便携产品。

四、典型应用场景

  • 单节锂离子 / 锂聚合物电池充电模块;
  • 可穿戴设备、智能手表、蓝牙耳机等小型便携设备;
  • 便携式医疗设备与传感模块;
  • 低功耗数据采集终端与物联网节点;
  • 需要自动充电管理且输入电源变化范围较大的系统。

五、系统设计建议

为保证充电器性能与系统安全,建议在设计时注意以下几点:

  • 输入电源能力:确保供电电源能稳定提供所需充电电流(最大 700mA),并留有一定裕量,避免输入电压因电流骤增而跌落;
  • 散热管理:线性充电器在高压差和大电流条件下会产生显著功耗,需评估 PCB 的散热能力,并在布局上为器件旁预留铜箔散热区或多层过孔以改善散热;
  • 充电电流设定:通过外接电阻等方式合理设定充电电流,综合考虑电池容量、充电速度与发热;对小型设备建议采用较低电流以降低温升;
  • 输入/电池旁路电容:参考数据手册配置合适的输入与电池端去耦电容以保证稳定性和瞬态响应;
  • 保护与指示:在系统中增加温度检测、输入保险元件(如熔断器 / PT)和状态指示(LED 或 MCU 引脚),提升可靠性与用户体验;
  • 安全规范:遵循电池与系统的安全规范,避免在超出温度/电流/电压范围下使用,电池管理系统需考虑充电终止、充电重试与异常处理策略。

六、封装与生产注意事项

TDFN-6-AL(2×2mm)小封装适合高密度 PCB 布局,但需遵循生产与焊接规范:

  • 推荐使用回流焊盘设计并参考厂商的 PCB layout 建议以降低焊接缺陷;
  • 选择 TR 卷带包装便于 SMT 自动化贴装;
  • 注意焊盘涂覆与焊膏用量,避免热阻过高导致器件过热。

七、总结

SGM40560-4.2XTDI6G/TR 是一款面向单节锂电池的紧凑型线性充电管理器件,适用宽输入电压并支持最高 700mA 的充电能力,4.2V 充电饱和电压及-40℃~+125℃ 的工作温度范围使其适合多种便携与工业级应用。设计时需综合考虑散热、输入能力与电池安全策略,参考厂商数据手册和布局指南以确保可靠运行。若需进一步的电气特性或典型应用电路图,建议参考 SGMICRO 的官方数据手册或联系供应商获取完整资料。

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.
