SP2526A-2EN-L/TR 产品概述

一、概述

SP2526A-2EN-L/TR 是由 MAXLINEAR(迈凌)推出的一款双通道 N 沟负载开关(PWR SWITCH),采用 SOP-8 封装,面向 3.0V 至 5.5V 电源域的电源控制场景。器件为 1:2 拓扑结构,支持单一输入对两路输出的电源控制,输入控制逻辑为低电平有效,适合电源开关、分配与电源管理的多种应用。

二、主要特性

  • 工作电压范围:3.0V 至 5.5V
  • 最大持续输出电流:600 mA(单通道)
  • 导通电阻(RDS(on)):110 mΩ(典型条件下)
  • 通道数:2(1:2 配置)
  • 控制逻辑:低电平有效
  • 保护功能:过热保护(OTP)、短路保护(SCP)、欠压保护(UVP)
  • 工作温度范围:-40℃ 到 +85℃
  • 封装:SOP-8,便于 PCB 布局与批量装配

三、功能说明

SP2526A-2EN-L/TR 以 N 沟场效应管为开关元件,通过外部逻辑控制引脚实现对两路负载的通断控制。器件在开启时具有较低的导通电阻,能在中等电流下保持较小的压降与功耗;内置的 OTP、SCP 与 UVP 可在异常工况下保护器件与下游负载,提升系统可靠性。低电平有效的控制特性便于与 MCU/FPGA 的 GPIO 直接接口(在 3.3V/5V 系统中广泛兼容)。

四、典型应用场景

  • 电池供电的便携设备电源分配(智能硬件、手持终端)
  • USB/外设电源开关与保护
  • 电源域切换与电源管理(电源序列、模块化电源控制)
  • 工业与通信设备的负载保护与电源隔离

五、设计建议与注意事项

  • 输入侧需配置适当的去耦电容以抑制开关瞬态与降低噪声;输出侧根据负载特性配置滤波/去耦电容以保证系统稳定。
  • 在考虑温升与可靠性时,应根据 PCB 散热能力对 600 mA 的最大持续电流进行热能限流与降额设计;必要时采用铜箔加厚或散热垫增强散热。
  • 对有较大冲击电流或启动浪涌的负载,建议在上电或开关瞬间限制输入电流(软启动、电阻/NTC 限流或外部恒流电路)。
  • 控制端为低电平有效,若需默认断开可在控制引脚拉高;需注意控制信号的电平与上拉方式以避免误触发。
  • 若系统需要更大电流,可考虑并联多个器件或选用更大电流等级的负载开关,同时需注意均流与热管理。

六、封装与订购信息

器件型号:SP2526A-2EN-L/TR
封装形式:SOP-8(表面贴装)
品牌:MAXLINEAR(迈凌)
适用于需兼顾体积、成本与保护功能的消费类与工业级电源管理设计。

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
