CA-IS3720CLS 产品概述

一、简介

CA‑IS3720CLS 是 Chipanalog(川土微)推出的一款高性价比两通道数字隔离器,采用 SOIC‑8 封装,面向工业级应用。器件提供精确时序、低功耗以及优秀的电磁兼容性能,可在需要电气隔离的数字信号接口中替代光耦,实现更高带宽与更长寿命的解决方案。

二、主要规格

  • 通道数:正向通道 2、反向通道 0(双通道单向隔离)
  • 最大数据速率:40 Mbps
  • 传播延迟(tpd):22 ns(典型)
  • 隔离耐压(Vrms):3750 V
  • 共模瞬变抗扰度(CMTI):150 kV/μs
  • 默认输出:低电平(失效安全输出)
  • 工作电压:VCCA 3.0 V ~ 5.5 V,VCCB 3.0 V ~ 5.5 V
  • 工作温度范围:-40 ℃ ~ +125 ℃
  • 封装:SOIC‑8

三、功能特性

  • 施密特触发器输入:提高抗噪性能,适合带抖动/噪声的信号环境。
  • 失效安全输出:输入开路或异常时输出保持低电平,便于系统故障判定与安全设计。
  • 高 CMTI 与高隔离电压:对恶劣共模干扰及高电压差环境具有良好抗扰能力。
  • 低功耗、低辐射:相比传统光耦,功耗更低、EMI 辐射更小,便于通过系统级 EMC 设计。

四、典型应用

适用于工业控制(PLC、驱动接口)、电机控制、逆变器与电源管理、通信接口隔离、数据采集与传感器隔离、车载与电池管理等对数字隔离与高抗扰性有要求的场景。

五、设计与使用建议

  • 电源去耦:在 VCCA 与 VCCB 近端各并联 0.1 μF 陶瓷电容,必要时加入 1 μF 旁路电容以抑制低频噪声。
  • PCB 布局:保证隔离沟槽或足够爬电距离,A/B 侧信号与电源明确分区,减少跨区走线。
  • 输入端滤波:对长线或高噪声信号可在输入端采用 RC 或共模滤波器配合施密特输入提高可靠性。
  • 失效安全考虑:器件默认输出为低电平,系统逻辑设计时应考虑该状态对上位电路的影响。
  • 热与可靠性:工作在高温或高干扰环境时,应评估散热与长期稳定性,遵循厂方推荐的工作条件。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
