COS1416R是科山芯创(COSINE)推出的单通道高性能MOSFET栅极驱动器,专为中小功率MOSFET的高效驱动设计。核心目标是在超小型封装下实现「高电流驱动能力+快速开关特性」,同时集成必要的保护功能,满足工业级应用对可靠性与紧凑性的双重需求。
高驱动电流能力
支持最大1.5A灌电流(IOL)与拉电流(IOH)——即使面对栅极电容较大的MOSFET,也能快速充放电,确保MOSFET可靠导通/关断,避免因驱动不足导致的「导通损耗增加」或「开关损耗过大」问题。
宽电压工作范围
电源电压覆盖4.5V~25V,兼容常见的5V、12V、24V系统电源,无需额外电平转换电路,适配多种应用场景的电源设计(如车载12V、工业24V系统)。
快速开关特性
典型上升时间(tr)与下降时间(tf)均为11ns,能有效缩短MOSFET的开关过渡时间,降低开关损耗,提升电源转换效率——尤其适合高频开关应用(如高频DC-DC变换器)。
兼容低功耗MCU输入
输入高电平(VIH)仅需1.8V,输入低电平(VIL)最高700mV,与主流MCU(如STM32、TI MSP430等)的输出电平完全兼容,无需电平匹配,简化系统设计。
欠压保护(UVP)
内置欠压锁定功能:当电源电压低于阈值时,自动关闭输出,防止因电源不足导致驱动能力下降,避免MOSFET处于半导通状态而烧毁,提升系统稳定性。
过热保护(可选)
部分版本集成过热保护(OPT):当器件结温超过设定阈值时,自动关断输出,防止器件过热失效,进一步增强极端环境下的可靠性。
超小型封装
采用SOT23-5封装,尺寸仅为2.9mm×1.6mm×1.1mm,比传统DIP封装缩小数倍,大幅节省PCB空间,适合对体积要求严格的便携设备或高密度电路设计(如智能手机辅助电源、小型工业模块)。
工业级温区
工作温度范围覆盖-40℃~+85℃,满足工业现场的「低温(户外设备)」与「高温(电源模块内部)」环境需求,可靠性符合工业级标准。
COS1416R的性能特点使其广泛适用于以下场景:
COS1416R作为一款高性价比单通道MOSFET驱动器,在小封装下集成了「高驱动电流、快速开关、宽电压范围+保护功能」,兼顾性能、可靠性与成本,是工业控制、电源设计、消费电子等领域中小功率MOSFET驱动的理想选择。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
