ISL61851EIBZ-T 产品概述

一、产品简介

ISL61851EIBZ-T 为 RENESAS(瑞萨)旗下的双通道热插拔控制器,采用 SOIC-8 封装,专为 USB 及类似外设电源线上电/热插拔管理设计。器件支持 2.3V ~ 5.5V 宽工作电压范围,工业级工作温度 -40℃ 至 +85℃,每通道独立工作,适合对可靠性和保护要求较高的系统。

二、主要特点

  • 双通道独立控制,节省 PCB 面积与元件数量;
  • 宽工作电压:2.3V ~ 5.5V,兼容多种供电拓扑与 USB 供电档位;
  • 工作温度范围 -40℃ ~ +85℃,满足工业和商用环境;
  • SOIC-8 封装,便于常规焊接与手工调试;
  • 针对热插拔场景的软启动与浪涌限流功能,降低对系统和端口的冲击。

三、典型功能与保护

ISL61851EIBZ-T 提供热插拔所需的一系列控制与保护功能,包括受控上电(软启动)以限制浪涌电流、过流/短路检测与快速响应、过温保护以及故障状态指示/故障输出信号。器件通常配合外部功率 MOSFET、分流电阻与 RC 网络,通过外部元件设定限流门槛与延时,灵活性高。

四、应用场景

  • 各类带 USB-A/USB-C 端口的主板、嵌入式主控板、充电器和扩展坞;
  • USB 集线器、工业通信设备、汽车车载娱乐与信息终端(在符合温度与电气规范范围内);
  • 需要端口热插拔保护的便携设备与外设供电管理场景。

五、设计与使用建议

  • 选择低 Rds(on) 的功率 MOSFET 以减少发热与功率损耗;
  • 根据目标最大电流选择合适电流检测电阻并调整 RC 延时以避免误动作;
  • 合理布线以保证电流回路最短、散热良好,并在 MOSFET 与电阻附近留足过热裕量;
  • 在系统级验证时进行上电冲击、短路恢复与热循环测试,确保保护动作与恢复符合预期。

六、封装与可靠性信息

ISL61851EIBZ-T 采用 SOIC-8 封装,便于量产组装与散热管理。器件在工业温度范围内长期可靠,适合需要稳定热插拔保护的各类产品。有关更详细的电气特性、引脚定义与典型应用电路,请参阅 RENESAS 官方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
