SGM42507B-1.75XC6G/TR 产品概述

一、概述

SGM42507B-1.75XC6G/TR 是圣邦微(SGMICRO)推出的一款适用于小功率电机保护与电源切换的功率开关器件,采用小型 SC-70-6 封装。器件工作电压范围为 1.9V 至 7.5V,典型导通电阻为 385 mΩ,工作温度范围为 -40℃ 至 +125℃。器件内置输入欠压保护与过流保护,适合便携式设备、微型马达驱动和对体积与可靠性有要求的应用场景。

二、主要规格(摘要)

  • 品牌:SGMICRO(圣邦微)
  • 型号:SGM42507B-1.75XC6G/TR
  • 封装:SC-70-6
  • 工作电压:1.9V ~ 7.5V
  • 导通电阻(RDS(on)):385 mΩ
  • 工作温度范围:-40℃ ~ +125℃
  • 功能特性:输入欠压保护、过流保护

三、关键特性与优势

  • 小体积封装:SC-70-6 适合空间受限的 PCB 布局,便于在移动设备和微型系统中集成。
  • 宽工作电压:1.9V 起始电压支持低电压供电平台(如单节锂电、低压 MCU 系统),上限 7.5V 满足多数小电机直流驱动需求。
  • 内置保护功能:输入欠压保护(UVP)可防止在电源不足时误导通或不稳定工作;过流保护(OCP)提高系统对短路或机械卡阻等异常工况的鲁棒性。
  • 温度范围广:-40℃ 至 +125℃ 适应工业与消费类环境温度需求。

四、典型应用场景

  • 小型直流电机驱动(如微型减速电机、风扇、振动马达)
  • 电池供电便携设备的电机电源开关
  • 电机驱动保护模块、负载切换与短路保护方案
  • 家电小功率驱动和工业小型执行器控制

五、设计与选型建议

  • 电流能力评估:RDS(on)=385 mΩ 在较高电流下会产生显著功耗。举例:在 1A 电流下,导通压降约 0.385V,功耗约 0.385W;请根据系统允许的温升和散热条件评估最大持续电流。
  • 欠压保护配置:确认系统供电在启动与工作过程中的电压波动是否会触发输入欠压保护,必要时加入软启动或上电延迟策略,避免频繁重置。
  • 过流保护响应:了解器件 OCP 的触发阈值与响应特性(脉冲耐受能力、重试/锁定行为),与系统的负载特性匹配,避免工作点误触发。
  • 外围器件:在器件输入端与输出端放置合适的去耦电容(低 ESR)以抑制瞬态和稳定供电;必要时在负载路径添加限流或熔断器作为冗余保护。

六、热管理与 PCB 布局要点

  • PCB 铜地/散热区:即使是小封装,增加器件引脚附近的铜箔面积或多层 PCB 的过孔热通道可显著降低结温上升。
  • 短且宽的导线:布线时尽量缩短电源与负载之间的走线长度并加宽,减小寄生阻抗和温升。
  • 去耦与滤波:靠近器件放置输入去耦电容,降低瞬态电压波动对欠压保护带来的影响,同时减小 EMI。
  • 测试点与调试:为电流和电压监测预留测试点,便于量测 OCP 行为与热特性验证。

七、总结

SGM42507B-1.75XC6G/TR 以其小型封装、宽电压范围和内置保护功能,适合用于小功率电机驱动及相关负载保护场合。选型时重点关注器件的导通电阻与热耗散限制、保护阈值与系统工作点的匹配。合理的 PCB 布局和必要的外围去耦、限流措施能显著提升系统稳定性与可靠性。若需更详细的电气参数(如 OCP 阈值、典型波形、引脚定义和典型应用电路),建议参考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.

Replenishment inquiry Typical RFQ workflow
