SGM457XKB6G/TR 产品概述

一、产品简介

SGM457XKB6G/TR 是圣邦微(SGMICRO)推出的一款高精度、低功耗的数字温度传感器,封装为 SOT-563-6。器件以数字 I2C/SMBus 接口输出温度信息,具有 ±0.5℃ 的精准度和 12-bit 分辨率,适合对体积、功耗和精度有较高要求的消费电子、工业与物联网终端。

二、关键规格

  • 温度精度:±0.5℃(典型/最大值请参照具体工况与数据表)
  • 工作电压:1.6V ~ 5.5V,兼容多种电源域
  • 通讯接口:I2C / SMBus,标准数字总线,易于 MCU 集成
  • 温度转换时间:26 ms(单次转换)
  • 温度分辨率:12 bit(细颗粒度温度读数)
  • 封装:SOT-563-6(超小型封装,适合空间受限设计)
  • 特色功能:温度阈值监测、硬件比较器/独立温控输出、可配置的温度输出、低功耗待机模式

三、主要功能亮点

  • 精确监测:±0.5℃ 精度与 12-bit 分辨率,满足环境温度与器件热特性监控需求。
  • 快速响应:26 ms 的转换时间适合需要较短响应延时的应用场景。
  • 硬件报警:内建比较器与独立温控输出,可配置上限/下限阈值,支持中断或硬件告警,减轻主控负担。
  • 宽电压与低功耗:1.6V~5.5V 的工作范围和待机模式,适配电池供电和多电压系统。

四、应用场景

  • 移动与可穿戴设备的温度管理
  • 电池包与充电器温度监控
  • 工业控制与家电温度保护
  • 服务器/通信设备的局部温度感知
  • 物联网节点、智能家居与便携测试设备

五、设计注意事项(建议)

  • I2C 总线:使用合适阻值的上拉电阻(典型 2.2k~10k),并注意总线速率与拉升时间匹配。
  • 电源处理:在 VCC 端靠近器件放置 0.1 µF 去耦电容,保证瞬态稳定性。
  • 热耦合与布局:SOT-563-6 为超小封装,响应快但受 PCB 热传导影响较大;若需精确点温度,器件应靠近被测点,避免被附近大铜箔或热源干扰。
  • 报警与功耗控制:利用硬件比较器输出与低功耗待机,能在保持监测功能的同时显著降低系统功耗。
  • 参照数据手册:寄存器映射、I2C 地址与电气参数请以官方数据手册为准,量产时建议评估温度误差随布局与自发热的变化并做必要校准。

六、结论

SGM457XKB6G/TR 以高精度、快速转换与丰富的硬件报警功能,配合超小 SOT-563-6 封装和宽电压、低功耗特性,是对尺寸与能耗敏感并需可靠温度监控的系统的理想选择。欲完成产品选型与开发,请下载并仔细阅读官方数据手册,确认寄存器、时序与封装引脚信息。

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
