MD7680AF0PA1 产品概述

MD7680AF0PA1 是明达微推出的一款超高压、超低静态电流的固定输出 LDO 稳压器,输出为正极 15V,单通道设计,适用于对功耗、可靠性与输入耐压有苛刻要求的工业、汽车电子及分布式供电系统。器件采用 SOT-89-3L 封装,集成多重保护与使能控制,便于系统电源管理与热稳定性设计。

一、核心性能亮点

  • 输入工作电压最高可达 60V,支持高压源直接供电,适合车载与工业总线等高压环境。
  • 固定输出 15V,输出电流最大 150mA,满足中等功率负载的稳压需求。
  • 优异的电源纹波抑制比(PSRR)为 80dB(100Hz),对电网噪声与开关源干扰有出色抑制能力。
  • 超低静态电流 Iq = 2.3μA,适合电池供电或长待机系统,可显著降低静态损耗。
  • 在轻载条件下表现出极低压差,标称压差仅 8mV(Iout=1mA),保证低压差下的输出精度与效率。

二、完整功能与保护机制

MD7680AF0PA1 内置完备的保护与控制功能,提升系统可靠性:

  • 使能控制(EN):外部逻辑可对稳压器进行快速使能/关断,实现电源管理与功耗优化(具体门限与时序请参阅数据手册)。
  • 过流保护(OCP)与短路保护:限制输出电流,防止负载短路或异常工况对芯片和后端系统造成损害。
  • 反极性电流保护:避免在输出端电压高于输入时发生反向电流,保护稳压器与负载。
  • 热关断(Thermal Shut-down):当芯片结温超限时自动关断输出,防止热应力导致器件失效。

三、封装与工作环境

  • 封装:SOT-89-3L,利于波峰/回流焊接与散热布局,在空间受限的应用中兼顾性能与封装尺寸。
  • 工作温度范围:-40℃ 至 +85℃(Ta),覆盖常见工业与车用环境温度等级。

四、典型应用场景

  • 汽车车载辅助电源(ECU 外围、传感器供电、车灯驱动低功耗模块)
  • 工业控制与自动化设备(高压总线降压、传感器供电、数据采集模块)
  • 分布式电源与边缘设备(远程传感器、低功耗计量设备、便携仪表)

五、设计与使用建议

  • 输入端建议加装旁路电容(如 0.1μF 陶瓷)靠近 VIN 引脚以滤除高频噪声,输出端配合合适的低 ESR 电容(如 1μF〜10μF 陶瓷或钽电容)以保证稳定性与瞬态响应。
  • 使能脚的逻辑电平及上拉/下拉设计请参考器件数据手册,避免在启动瞬间出现不确定状态。
  • 在高压输入或大功耗条件下注意 PCB 散热设计,保持封装散热路径通畅,必要时增大铜箔面积或使用散热垫。
  • 若系统存在反向供电或输出回流情形,器件的反极性电流保护与短路保护可以提供额外的安全保障,但仍建议在系统层面做整体保护设计。

总结:MD7680AF0PA1 将超高输入电压容限、极低静态电流与丰富的保护特性集成在小尺寸封装内,适合对可靠性、能耗与输入耐压有高要求的应用场合。详尽电气特性、引脚定义与典型应用电路请参见明达微正式数据手册与应用说明书。

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
