PCA9306GF,115 产品概述

一、产品简介

PCA9306GF,115 是恩智浦(NXP)推出的一款双通道双向电压电平转换器,适用于不同电压域之间的 I2C/SMBus 或开漏信号接口电平匹配。器件支持自动方向检测,采用单芯片两通道设计,封装为 XSON-8 体积极小,适合空间受限的便携与嵌入式系统。

二、主要规格

  • 通道类型:双向(自动方向检测)
  • 通道数:每芯片 2 通道
  • 输出类型:开漏(需外部上拉电阻)
  • 工作电压:VCCA = 1.0 V ~ 3.6 V;VCCB = 1.8 V ~ 5.5 V
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:XSON-8(小尺寸封装,适合高密度 PCB 布局)
  • 品牌:NXP(恩智浦)
  • 型号示例:PCA9306GF,115

三、功能与工作原理要点

PCA9306 通过内部 MOSFET 结构和外部上拉网络实现双向电平转换,无需额外方向控制信号,能够在两侧电平差异存在时自动传递低电平和高电平信息。输出为开漏结构,器件并不主动驱高,需在两侧分别配置合适的上拉电阻到对应的 VCCA/VCCB。该结构特别适合 I2C 等双向开漏总线的透明电平匹配。

四、典型应用场景

  • 不同供电域之间的 I2C/SMBus 互联(如 1.0V/1.8V 内核与 3.3V/5V 外设)
  • 低电压 MCU 与传感器、EEPROM、RTC 等外设接口
  • 手机、可穿戴设备、物联网终端、消费电子和工业控制中的总线电平隔离与互通

五、设计与使用建议

  • 上拉电阻:根据总线速率与负载选取合适阻值,常见值范围在 2.2 kΩ 到 100 kΩ;高速场合需减小阻值以改善上升时间。
  • 去耦电容:在 VCCA 与 VCCB 近端各放置陶瓷去耦电容(如 0.1 µF)以稳定供电。
  • 布局注意:保持总线线长最短,减小串扰与寄生电容,确保双向 MOSFET 节点周围走线清晰。
  • 温度与可靠性:工作温度范围 -40 ℃~+85 ℃,适用于绝大多数商业与工业级应用环境。
  • 兼容性:适配 I2C/SMBus 典型速率,使用前确认系统总线速率与上拉组合满足时序要求。

六、产品优势概述

PCA9306GF,115 以小封装实现双通道双向转换,支持广范围电压供给和自动方向检测,简化了多电压系统的设计复杂性。开漏输出与 I2C 总线固有特性天然兼容,适配性强,封装适合高密度板级实现,便于在移动与嵌入式产品中广泛使用。

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
