MAX20087ATPA/VY+T 产品概述

一、概览

MAX20087ATPA/VY+T 是 ADI/Linear 提供的一款面向汽车摄像头供电保护的高侧开关器件(Camera Power Protectors),采用 20 引脚 TQFN-EP (4×4 mm) 封装并满足 AEC‑Q100 可靠性要求。器件集成四路独立高侧开关,专为车载摄像头、电源分配与保护场景设计,兼顾尺寸、保护功能与热性能。

二、主要电气参数

  • 通道数:4 路高侧开关
  • 工作电压范围:3 V ~ 15 V
  • 最大连续电流(每通道):600 mA
  • 导通电阻 RDS(on):700 mΩ(典型)
  • 输入控制逻辑:高电平有效
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 封装:TQFN-20-EP (4×4)

在 600 mA 负载下,单通道导通损耗约为 0.6^2 × 0.7 ≈ 0.252 W,布局与散热需考虑该功耗对芯片及 PCB 温升的影响。

三、保护与功能特性

MAX20087 提供全面的保护机制,适应车规复杂电源环境:

  • 短路保护(短路/大电流检测)
  • 过流保护(限制或关断以防损坏)
  • 过温保护(热关断或限流,防止热失控)
  • 过压保护与欠压锁定(保护下游器件并避免异常上电)
  • 软启动(限制上电涌流,对摄像头等负载友好)

这些功能可显著降低系统故障风险并简化外部保护电路设计。关于保护行为(自动恢复或锁定)和阈值,请参考器件数据手册以确定在具体故障条件下的响应机制。

四、典型应用

  • 汽车摄像头电源管理(后视、环视、ADAS 摄像头)
  • 汽车信息娱乐与辅助电源分配
  • 多路低功率外设供电开关,需在车规温度与瞬态环境下可靠工作

五、设计注意事项与建议

  • 电源与旁路:在器件 VIN 端和每一路输出处放置低 ESR 陶瓷去耦电容,靠近封装焊盘布置以抑制瞬态。
  • 热管理:为 TQFN 底部散热垫设计足够的焊盘过孔与铜层,必要时在 PCB 下层扩展散热铜箔并使用多层接地平面以降低温升。
  • 控制接口:控制引脚为高电平有效,确保控制电平与系统逻辑兼容;必要时加入上/下拉网络以定义复位态。
  • 保护策略:尽管器件内置多种保护,系统层面仍建议配合熔丝、限流器或监测 MCU 以实现更完善的故障处理与诊断。
  • 布线与 EMI:高侧开关切换与保护动作可能引起瞬态,保持敏感信号走线远离电源转换节点,必要时加入滤波与共模抑制措施。

六、采购与封装信息

  • 品牌:ADI (Analog Devices / Linear)
  • 零件号:MAX20087ATPA/VY+T
  • 封装:TQFN-20-EP (4×4 mm)
  • 认证:AEC‑Q100(适用于车规级应用)

结语:MAX20087ATPA/VY+T 将多路高侧开关与完整的保护功能集成于紧凑车规封装中,适合需要小尺寸、高可靠性与多重故障保护的车载摄像头和分布式低功率电源系统。选择与布局时应重点关注散热、去耦与控制兼容性;详细电气特性与门限请以官方数据手册为准。

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
