SP809EK-L-2-9/TR 是由 EXAR(艾科嘉)公司推出的一款高性能监控和复位芯片。此芯片专为电子设备的电源管理而设计,能够在电力供应不稳定时提供可靠的复位功能,以确保设备的正常运行。其安装类型为表面贴装型(SMD),适合在现代电子产品小型化和低成本要求下应用。
监控电压: SP809EK-L-2-9/TR 的电压阈值为2.9V,能够有效监控电源供电状况。当输入电压降至2.9V以下时,芯片会及时发出复位信号,防止因电源不足而导致的数据损坏或系统崩溃。
输出特性: 该芯片采用推挽式/图腾柱输出方式,可以提供较强的推挽能力,适合驱动较大负载。其复位信号为低有效,这为用户在设计电路时提供了灵活性,可以轻松集成到多种系统中。
复位超时: SP809EK-L-2-9/TR 的复位超时时间最小为140ms,确保在电源恢复后,系统有足够时间稳定下来再进行正常操作。这一特性在复杂的数字电路中尤为重要,可以显著提高系统稳定性。
工作温度范围: 产品的工作温度范围为-40°C至85°C,适应了恶劣环境下的应用需求。无论是在极端的寒冷条件还是高温环境中,该芯片都能维持良好的工作性能。
封装与安装: SP809EK-L-2-9/TR 采用 SOT-23-3 封装,体积小巧,适合高密度的电路板设计。这种表面贴装封装形式使得该芯片能够方便地被集成进各种电子产品中。
SP809EK-L-2-9/TR 产品广泛应用于以下几个领域:
消费电子产品: 例如智能手机、平板电脑、笔记本电脑等,能够有效防止低电压对电路造成影响。
工业控制设备: 在工业自动化系统中,保证设备在电源供应稳定时正常工作,降低故障率。
医疗设备: 对于需要高可靠性的医用电子设备,监控和复位功能可以提供重要的安全保障。
汽车电子: 现代汽车中的各种电子控制单元(ECU)需要稳定的供电,多种传感器和模块的电源监控即可借助该芯片。
无人机和机器人: 由于在复杂和变化多端的环境中工作,需要确保电源的稳定性和及时的复位操作。
SP809EK-L-2-9/TR 是一款性能稳定、适用广泛的监控和复位芯片,结合了高可靠性和全面的工作范围。凭借其卓越的设计和良好的热稳定性,能够在多种严酷环境下保持最佳性能,为各种电子产品提供强有力的支持。使用 SP809EK-L-2-9/TR 可显著提升系统的稳定性与可靠性,是电子工程师在电源管理设计中不可或缺的选择。其 полное соответствие международным стандартам и превосходная электроника делают его надежным и эффективным решением для современных технологий.
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
