JH4是钜兴(JUXING)针对宽温环境下小功率恒流负载驱动推出的单通道集成芯片,聚焦工业级、车载辅助及消费电子领域的可靠性与成本优化需求,凭借高集成度、宽温适配及保护特性,成为同类场景下的高性价比选择。
JH4定位于小功率单路恒流驱动专用芯片,核心应用围绕需要稳定恒流输出、宽温工作的负载场景,典型包括:
其单通道设计适配单负载驱动,避免多通道冗余成本,精准匹配小功率需求。
JH4的核心参数聚焦“稳定、宽温、集成”三大方向,关键指标及实际意义如下:
JH4内置功率开关管,外围仅需1~2个滤波电容及限流电阻(部分场景可省略),BOM成本降低30%以上;ESOP-4封装尺寸仅2.9×4.9mm,缩小PCB占用面积40%,适合高密度布局。
采用高温稳定BCD工艺,-40℃~+125℃范围内输出电流漂移控制在±3%以内(优于常规±5%精度),避免LED亮度因温度变化忽明忽暗,适配工业烤箱、车载高温舱等极端环境。
内置OTP保护机制:结温超150℃时自动切断输出,温度回落至120℃以下自动恢复,有效防止过载/散热不良导致的烧毁,延长2倍以上使用寿命。
静态电流仅10μA(典型值),适合电池供电设备(如智能门锁指示灯),单次充电可支持指示灯工作1000小时以上。
JH4采用ESOP-4超薄小外形封装,具备三大可靠性优势:
JH4针对小功率恒流驱动痛点,形成核心竞争力:
目前JH4已通过AEC-Q100(车载级)及ISO 9001(工业级)认证,量产良率达99.8%,可满足批量供货需求。
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.
