P14C5N 产品概述
P14C5N 是 Prisemi（芯导）推出的一款可调过压保护（OVP）负载开关，内置功率 MOSFET，与过压锁定（OVLO）逻辑结合使用，以在输入电压异常升高时快速断开负载，保护下游电路与器件。
一、主要参数
- 漏源电压 Vdss：30 V
- 连续漏极电流 Id：3 A（额定）
- 导通电阻 RDS(on)：70 mΩ @ Vgs = 5 V
- 栅极耐压 Vgs：±6 V
- 工作温度范围：-40 ℃ ~ +85 ℃
- 封装：DFN2x2-8L
- 品牌：Prisemi（芯导）
二、功能与工作原理
P14C5N 将输入（IN）与输出（OUT）之间的电流通过内部 MOSFET 控制，当任一输入电压超过设定的 OVLO 阈值时，器件会触发过压锁定，关闭内部 MOSFET，断开 IN 与 OUT 的连接，从而保护后端负载。OVLO 阈值支持外部可调：通过 OVLO 输入接入电阻分压或参考电压可设定所需触发电平；当 OVLO 输入被拉低至低于外部 OVLO 选择电压时，器件可自动采用内部固定的 OVLO 阈值，实现简易的两档保护选择。
三、封装与布板建议
DFN2x2-8L 小尺寸封装适合空间受限的应用。为保证热性能和导通能力，建议在 PCB 上为器件底部焊盘和电源走线提供足够的铜箔面积与散热通孔；输入侧建议并联去耦电容以抑制瞬态及减少 EMI。布线应尽量短而宽，降低寄生电阻与感抗。
四、典型应用场景
- 移动电源与充电器的输出过压保护
- 电池供电系统与电源管理模块
- 工业和通信设备的局部电源保护
- 对电压超限敏感的传感器或控制电路的前端保护
五、设计与使用建议
- 根据最大工作电流与功耗评估温升并选择合适 PCB 散热布局；在高电流场景下考虑并联多个器件或降低 MOSFET 的 RDS(on)。
- OVLO 阈值通过外部分压器设定时应选用高精度电阻以保证触发精度，并考虑温漂影响。
- 注意 Vgs ±6 V 限制，避免在控制端施加超出范围的瞬态电压。
- 负载开关恢复策略、上电顺序与故障指示（如需）应在系统级设计中考虑，必要时配合上拉/下拉立即复位电路或状态检测逻辑。
P14C5N 适合需要可靠、可配置过压保护的紧凑型电源管理应用，结合合理的 PCB 布局与外部阈值设定，可实现对后端电路的高效保护。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
