BL8506-40CRM 产品概述

一、简介

BL8506-40CRM 是贝岭(BELLING)推出的一款单路电压监测与复位芯片,封装为 SOT-23。器件在被监控电压低于设定阈值时输出低电平复位信号,用于微控制器、数字系统的上电复位与欠压保护。器件工作电压范围宽(0.7V–10V),静态电流极小(Iq ≈ 1 μA),适合电池供电与低功耗应用。

二、主要特性

  • 输出类型:推挽(Push-Pull),无需外部上拉电阻;
  • 复位有效电平:低电平有效(Active Low);
  • 门限电压(标称):4.0 V;
  • 复位超时(释放延时):约 20 μs;
  • 看门狗定时器:无;手动复位引脚:无;
  • 监控通道数:1 路;
  • 工作电压范围:0.7 V ~ 10 V;
  • 工作温度范围:-40℃ ~ +85℃(Ta);
  • 封装:SOT-23;品牌:BELLING(贝岭)。

三、功能说明

当被监控电压低于 4.0V 标称阈值时,BL8506-40CRM 将主动将复位输出拉低,保持系统处于复位状态;当电压回升并稳定超过阈值后,器件在内部设定的复位超时时间(约 20 μs)后释放复位,输出回到高电平。推挽输出可主动给出高、低电平,方便直接驱动微控制器复位脚或逻辑电路。

四、典型应用

  • MCU/MPU 上电复位与欠压保护;
  • 电池供电的便携设备、传感节点;
  • 电源管理与电源顺序控制;
  • 工业控制、通信设备的可靠复位电路。

五、封装与引脚

SOT-23 小封装,三脚排列,常见引脚功能为 VCC、GND、RESET(推挽输出)。在布局时应将 GND 引脚尽量靠近系统地,并在 VCC 引脚处放置合适的旁路电容以抑制瞬态干扰。

六、使用建议与注意事项

  • 由于为推挽输出,通常无需外加上拉电阻;若需与不同电平域接口,注意电平兼容性;
  • 没有手动复位引脚,如需外部复位按钮,可在 RESET 与地之间加短接电路或采用外置逻辑;
  • 建议在 VCC 处并联 0.1 μF 陶瓷电容以提高抗干扰能力;在存在较大浪涌或电磁干扰环境下考虑在输入端增加抑制元件(如 TVS、限流电阻)。
  • 器件静态电流极低,适合长期电池工作,但在极端温度或快速电压跃变时应在系统层面验证复位时序。

七、订购信息

型号:BL8506-40CRM,封装:SOT-23,生产厂商:BELLING(贝岭)。购买与技术支持建议通过正规代理或厂商渠道获取,以保证原厂质量与最新数据手册。

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
