TJA1463ATK/0Z 产品概述

一、概述

TJA1463ATK/0Z 是恩智浦(NXP)面向汽车电子的 CAN-FD 器件——CAN SIC(Signal Improvement Circuit)收发器,集成低功耗睡眠功能。该器件支持高达 8 Mbps 的 CAN-FD 数据速率,工作电压范围 4.5 V 至 5.5 V,适配现代车载网络对更高带宽与更强鲁棒性的需求。

二、主要参数与优势

  • 类型:CAN-FD 收发器,带睡眠模式(CAN SIC TRANSCEIVER WITH SLEEP)
  • 数据速率:最高 8 Mbps,满足 CAN-FD 应用的高速通信需求
  • 工作电压:4.5 V ~ 5.5 V,兼容典型车载 5 V 总线域
  • 工作电流:典型 70 mA(正常工作态),设计时应考虑功耗及散热
  • 静态电流:26 µA(低功耗睡眠态),利于待机节能与电瓶管理
  • 工作温度:-40 ℃ ~ +150 ℃,覆盖严格的汽车温度等级
  • 封装:HVSON-14-EP (3 × 4.5 mm),带底部散热焊盘,利于热管理与占板优化

器件采用 SIC 技术,可提高总线共模抑制和信号完整性,使在复杂电磁环境下的链路更稳定;同时集成睡眠及唤醒机制,便于车载控制单元的低功耗设计。

三、典型应用场景

  • 车身域控制器(BCM)、车门/座椅/照明等域网通信
  • 网关与域控制单元间的高速 CAN-FD 链路
  • 电机控制器、车载诊断接口(OBD)、充电管理系统等需要高带宽与可靠通信的模块
  • 需严格控制待机耗电的系统(凭借 26 µA 静态电流)

四、封装与布局建议

HVSON-14-EP 封装带有底部引脚(EP)用于散热。建议在 PCB 设计中:

  • 在底部焊盘下设计适当的热释孔(thermal vias)连通内层铜箔以增强散热
  • 在 VCC 附近放置高频并联去耦(如 0.1 µF + 1 µF),靠近器件引脚布置
  • CAN_H/CAN_L 端应考虑 120 Ω 终端电阻及浪涌抑制器件(如 TVS),提高抗瞬态能力

五、设计注意事项

  • 电源与地的回流路径需尽量短、截面积足够,减少 EMI 与电压降
  • 睡眠/唤醒逻辑与微控制器接口需明确时序,避免误唤醒或长时间总线占用
  • 在高数据率下注意差分对长度匹配与阻抗控制,确保 8 Mbps 信号完整性
  • 考虑器件在工作电流 70 mA 下的功耗与热沉布置,特别是在高温工况

六、可靠性与选型建议

器件工作温度范围宽(-40 ℃ ~ +150 ℃),适合严苛汽车环境。选型时建议结合系统电源、故障保护与 EMI 要求,与 PCB 工艺供应商确认 HVSON-EP 的焊接工艺规范以保证可靠性。

七、总结

TJA1463ATK/0Z 是一款面向汽车 CAN-FD 网络的高性能收发器,兼顾高速通信(8 Mbps)与低功耗待机(26 µA),工作电压 4.5–5.5 V、工作电流约 70 mA, HVSON-14-EP 小型封装便于模块化设计。适用于需要高带宽、严格温度与低待机功耗的车载网络系统。在具体设计中应关注电源去耦、差分匹配、终端并采取适当的浪涌与静电防护措施,以确保系统稳定可靠。

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
