CA-IS3641LW 产品概述

一、概述

CA-IS3641LW 是 Chipanalog(川土微)推出的一款集成隔离电源的四通道高性能数字隔离器。器件在单芯片内同时实现数据隔离与隔离电源输出,适用于需要信号隔离和供电隔离的工业与电力电子场景,可显著简化系统设计与物料清单。

二、主要特性

  • 正向通道:3;反向通道:1(总共四通道,适合半双工或方向不对称的接口)。
  • 最大数据速率:100 Mbps,满足高速数字通信需求。
  • 默认输出电平:低电平(未驱动时输出为低)。
  • 集成隔离电源工作电压:3.0 V ~ 5.5 V;集成隔离电源输出:5 V 和 3.3 V(片上提供隔离侧电源,简化二次供电)。
  • 隔离电压(Vrms):5000 V,物理隔离等级高。
  • 共模瞬变抗扰度(CMTI):150 kV/µs,适合高干扰环境。
  • 工作温度范围:-40 ℃ ~ +125 ℃。
  • 封装:SOIC-16-WB,利于标准化 PCB 布局与自动贴片。

三、技术规格要点

该器件在高共模瞬变环境下保持逻辑完整性,100 Mbps 的带宽适配工业以太网、隔离 UART、SPI 等接口。集成隔离电源能为隔离侧外围器件提供 5V/3.3V 供应,便于构建独立接地的二次侧电源域(具体输出电流请参照完整数据手册以确定负载能力)。

四、典型应用

  • 工业控制与 PLC 隔离通信
  • 电机驱动、逆变器与变频器的控制信号隔离
  • 隔离的现场总线、串口和 SPI 接口
  • 电源测量与数据采集系统(隔离测量通道)

五、设计与使用建议

  • 在隔离电源输出侧配置适当的去耦电容与旁路电容,抑制切换噪声与维持瞬态响应。
  • 维持主从侧的走线、接地与敏感信号的物理分离,遵守器件推荐的爬电距离与间隙。
  • 高 CMTI 场合注意差分布局与共模抑制,避免长的并行走线跨越隔离缝。
  • 未使用的输入/输出应根据默认输出策略处理(默认低电平),建议拉到定义电平以避免浮动。
  • 关注热耗与封装散热路径,必要时在 PCB 上添加散热铜箔。

六、封装与可靠性

SOIC-16-WB 兼容常见工业焊接与封装流程,器件在-40 ℃ 到 +125 ℃ 的工作温度范围内保证稳定性。5000 Vrms 的隔离强度及 150 kV/µs 的 CMTI 指标,使 CA-IS3641LW 能在严苛工业环境中长期可靠运行。

总结:CA-IS3641LW 将高速数字隔离与片上隔离电源结合,适合需要高抗扰度和简化二次供电的工业与电力电子应用。选择时请结合系统对隔离电源输出电流及详细时序的要求,参考完整数据手册以完成最终设计验证。

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
