PCA9552PW,118 是恩智浦(NXP)推出的一款 16 通道 LED 驱动器 IC,采用 TSSOP-24 封装,面向需要集中、可编程调光控制的各类照明与指示灯应用。器件工作电压范围为 DC 2.3V ~ 5.5V,支持 I²C 总线通信(最高速率 400kHz),单通道最大输出电流可达 25mA,工作温度范围为 -40℃ ~ +85℃,适合工业与消费类产品的常规温度场景。
PCA9552 通过标准 I²C 命令对内部寄存器进行读写,实现对各输出通道的开/关与亮度控制。典型的应用中,MCU 通过 I²C 总线直接下发亮度值或模式参数,从而完成单通道或多通道的渐变、闪烁与分组调光。I²C 最大 400kHz 的通讯速率能够满足多数实时显示与指示灯控制的响应需求。
器件采用 TSSOP-24(24 引脚窄体塑封)封装,占板面积小,便于高密度器件排布。常见引脚包括电源 (VCC/GND)、I²C 接口(SDA/SCL)、多个 LED 输出引脚及必要的模式/地址选择引脚(具体引脚定义请参阅官方数据手册)。
订购型号:PCA9552PW,118(NXP),封装 TSSOP-24。设计与选型时请以 NXP 官方数据手册为准,参考其电气特性、引脚定义、典型应用电路与 PCB 布局建议。如需样片测试,建议结合评估板或参考设计进行验证。
如需我帮您梳理基于该器件的典型电路、布局建议或并联多通道热分析,我可以基于具体应用场景给出更详细的工程建议。

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.
