AO6604 产品概述

一、简介

AO6604 是友台半导体(UMW)推出的一款双通道 MOSFET(N 沟道 + P 沟道)器件,采用先进沟槽工艺与低电阻封装技术,集成于 SOT-23-6 封装,专为便携电源管理、负载开关与电池保护场景设计,提供极低的导通电阻和紧凑的系统级解决方案。

二、主要参数

  • 漏源电压 Vdss:N / P 都为 20V
  • 连续漏极电流 Id:N = 3.4A;P = 2.5A
  • 导通电阻 RDS(on):N = 51 mΩ @ Vgs=4.5V;P = 56 mΩ @ Vgs=-4.5V
  • 功率耗散 Pd:N / P = 1.1W
  • 阈值电压 Vgs(th):N ≈ 0.7V;P ≈ 0.65V
  • 总栅极电荷 Qg:N = 2.9 nC @4.5V;P = 8.5 nC @4.5V
  • 输入电容 Ciss:N = 260 pF;P = 560 pF
  • 反向传输电容 Crss:N = 27 pF;P = 70 pF
  • 输出电容 Coss:N = 80 pF;P = 48 pF
  • 工作结温:-55℃ ~ +150℃
  • 封装:SOT-23-6

三、关键特性

  • 低 RDS(on):沟槽工艺与低阻封装带来较小导通损耗,利于延长电池续航与降低热升。
  • 互补双通道:N/P 配对便于实现高效电源路径切换、正负载隔离与倒灌防护。
  • 适配低压系统:20V 耐压适合 1-cell 至多串电池及移动设备电源管理。
  • 开关性能权衡:N 通道具有较低 Qg 与 Ciss,有利于快速驱动;P 通道 Qg 与 Crss 偏高,需考虑驱动能量与开关损耗。

四、典型应用场景

  • 电池保护电路(反向保护、放电/充电回路隔离)
  • 便携设备负载开关与电源路径切换(PMIC 辅助开关)
  • 电源域隔离与双向电流控制(与控制逻辑配合实现低压降切换)
  • LED 驱动、传感器供电断电控制等低压功率管理场合

五、封装与热设计

SOT-23-6 紧凑封装适合空间受限的 PCB 布局。器件 Pd 标称为 1.1W,实际热阻与 PCB 散热、焊盘面积及环境温度密切相关。建议在布局时:

  • 使用较大的焊盘和短厚铜过孔以提升散热能力;
  • 在高散热需求处增加热沉层或多层铜厚;
  • 保持电流回路短且粗,以降低导线电阻与寄生电感。

六、使用建议与注意事项

  • 驱动电压:标称 RDS(on) 在 ±4.5V 测试,推荐在接近此驱动电平下使用以获得标称导通损耗;在 3.3V 或更低电平下需验证导通性能。
  • P 通道栅极电荷与 Crss 相对较大,快速开关时可能产生较高的开关损耗与寄生振荡,建议适当串联门极电阻并优化布局以抑制振铃。
  • 注意最大 Vgs 与浪涌电压(器件手册中给出具体极限),并在必要时增加 TVS 或 RC 吸收网络保护。
  • 并联使用需注意均流问题;若用于高电流路径,优先考虑热设计与均流措施。

AO6604 在低压便携电源管理和电池保护领域提供了一种集成度高、性能均衡的解决方案。选型时建议结合目标系统的驱动电平、开关频率与散热条件进行详细评估。

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
