PCA9513ADP,118 产品概述

一、概述

PCA9513ADP,118 是恩智浦(NXP)推出的一款单通道双向 I²C 总线缓冲器/加速器,适用于需提升总线驱动能力和抗容性负载的 I²C/SMBus 系统。器件工作电压范围为 2.7V~5.5V,支持高达 400 kHz 的传输速率,封装为 TSSOP‑8,工作温度范围为 -40℃ 至 +85℃,适合工业级应用。

二、关键规格

  • 工作电压:2.7 V 至 5.5 V
  • 通道类型:双向(I2C/SMBus 兼容)
  • 最大下拉电流 (IOL):3 mA(单端有效驱动能力)
  • 静态电流 (Iq):典型 16 µA(低功耗)
  • 传播延迟 (tpd):80 ns @ 100 pF(快速响应)
  • 支持速率:最高 400 kHz(Fast-mode)
  • 封装:TSSOP‑8
  • 工作温度:-40 ℃ ~ +85 ℃

三、功能与优势

  • 缓冲与加速:在总线上引入缓冲器可有效减小器件对上拉电阻和总线电容的敏感度,改善上升/下降边沿,提升总线速率和可靠性。
  • 双向透明:保持 I²C 双向数据特性,支持主/从器件正常通信而无需额外方向控制。
  • 低功耗:待机静态电流约 16 µA,适合对能耗敏感的系统。
  • 宽电压范围:2.7V~5.5V 兼容常见单电源系统,便于与不同电平器件配合(注意非专用电平转换器的限制)。

四、典型应用场景

  • 多从机或长线的 I²C 总线扩展与分段,降低负载影响,提升系统稳定性。
  • 嵌入式主控与外设(传感器、EEPROM、ADC/DAC 等)之间的可靠连接。
  • 工业控制、通信设备、消费电子等对温度范围和稳态性能有要求的场合。

五、使用建议

  • 在系统设计中根据总线电容和节点数量选择合适的上拉电阻,搭配 PCA9513 可实现更高的速率和更好的信号完整性。
  • 器件为单通道缓冲器,若需多段隔离或更多通道,应并行或选用多通道器件。
  • 注意 PCB 布线和地线管理以减少噪声耦合,保证传播延迟与时序裕量匹配系统需求。

PCA9513ADP,118 以其低功耗、快速响应和工业级温度特性,适合需要提高 I²C 总线性能的各类应用,是对总线驱动能力与可靠性要求较高设计的合适选择。

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
