UJA1023T/2R04/C,51是恩智浦(NXP)针对LIN2.0协议从节点设计的收发器,专注于汽车电子及工业级低功耗通信场景。作为LIN总线网络的物理层接口器件,它实现了微控制器(MCU)与LIN总线之间的信号转换(逻辑电平↔总线电平),同时集成低功耗、宽电压、高可靠性等特性,可满足严苛环境下的稳定通信需求。
支持5.5V至27V的输入电压范围,完美覆盖汽车12V电源系统的典型波动(如发动机冷启动时电压跌落至6V以下、负载突变时电压升至24V以上),无需额外稳压电路即可稳定工作,简化系统设计成本。
正常工作模式下仅需65uA的典型电流,休眠模式下功耗进一步降低(符合汽车级待机需求),适合车窗、座椅、传感器等长期待机的车身节点,有效延长车辆电池续航时间。
支持最高20Kbps的数据传输速率,完全兼容LIN2.0协议规范,满足低速传感器(如温度、位置传感器)的实时数据传输,同时降低总线负载,提升网络抗干扰能力。
工作温度覆盖-40℃至+125℃,符合汽车电子AEC-Q100 Grade 1标准,可在发动机舱高温(125℃)、冬季低温(-40℃)等极端工况下稳定运行,适配汽车及工业严苛环境。
内置±8kV静电放电(ESD)保护电路,可抵御人体接触、设备插拔时的静电冲击,降低现场因ESD导致的器件失效风险,提升系统可靠性。
UJA1023T/2R04/C,51主要应用于低功耗、低速通信的汽车及工业领域:
采用16引脚小外形封装(SO),尺寸紧凑(典型7.8mm×3.9mm),适合高密度PCB布局,兼容表面贴装工艺,便于自动化生产。
恩智浦作为全球汽车电子领域的领先厂商,其LIN收发器产品经过多年市场验证:
该器件凭借低功耗、宽电压、高可靠性等特性,成为汽车车身控制及工业低功耗通信的优选LIN从收发器。
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.
