BD8388FV-ME2 是 ROHM(罗姆)推出的一款 8 通道线性 LED 驱动器 IC,集成移位寄存器与 PWM 调光功能,适用于 3.0V 至 5.5V 的直流供电环境。器件为 SSOP-16(4.4mm)封装,工作温度范围宽(-40℃ ~ +125℃),每通道最大输出电流 50mA,开关管为内置结构,便于系统集成与小尺寸 PCB 布局。
适用于按键背光、指示灯阵列、仪表盘与面板背光、信号/装饰照明以及工业与车载等需在 -40℃ 至 +125℃ 环境下可靠工作的场合(注:具体车规认证需参考数据手册与供应商说明)。
SSOP-16(4.4mm)封装适合标准表面贴装工艺,焊接时遵循 ROHM 建议的回流曲线及焊盘设计,可通过增加铜面积改善散热,但注意避免超出 PCB 工艺可接受范围。
总结:BD8388FV-ME2 以其 8 通道线性恒流、移位寄存器扩展能力及 PWM 调光功能,为中小功率、多通道 LED 控制提供了集成度高、易于布线的解决方案。设计时重点关注热管理与电源退耦,即可在苛刻温度环境下稳定运行。若需更详细的管脚定义、电气特性曲线及应用电路,请参考 ROHM 官方数据手册。

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.
