HT16H25-100LQFP 产品概述
HT16H25-100LQFP 是台湾 HOLTEK（合泰/盛群）推出的一款高集成度 LED 显示驱动控制器，适用于大尺寸点阵或多段式 LED 面板。器件集成升压电路与振荡器，支持 I²C 与 3 线串行接口，工作电压范围宽（2.4V〜5.5V），在低功耗与高驱动能力之间取得良好平衡，适合便携与工业级显示应用。
一、主要规格亮点
- 工作电压：2.4V〜5.5V
- 接口类型：I²C；3 线串行接口
- 静态/待机电流：约 5 μA
- 显示配置：60 × 16 bit（可直接驱动大尺寸点阵）
- 驱动时钟/频率：245.76 kHz
- 偏压选择：1/5、1/4、1/3、1/2、1/1（多级亮度/线性化调整）
- 工作温度：-40 ℃〜+85 ℃
- 功能特性：内置升压电路、内置振荡器
- 封装：LQFP-100（14 × 14 mm）
二、功能与优势
HT16H25 集成化程度高，内置升压电路可直接为 LED 提供足够驱动电压，降低外部升压元件数量；内置振荡器与 245.76 kHz 的驱动时钟支持稳定的多路扫描与 PWM 调光，偏压可选项有利于亮度与功耗的折中设计。此外器件待机电流低（约 5 μA），非常适合电池供电的便携终端。
三、接口与控制
器件同时支持标准 I²C 总线与三线串行控制，便于与 MCU/主控系统通信与集成。在 I²C 模式下可实现多芯片寻址与总线共享；三线模式在简单控制或对实时性要求较高的场景中可降低通信开销。使用时需在 I²C 总线上配置合适的上拉电阻，并根据时序手册设定通信速率与时序约束。
四、典型应用
- 仪器仪表与工业控制面板的大尺寸点阵显示
- 手持设备、智能家居、便携终端的图形/文字显示
- 消费类电器与医疗设备的状态/信息显示
- 需要低功耗与高可靠性的户外或车载显示（在合适的封装防护下）
五、设计注意事项
- 外围布局：尽量靠近 VDD/AGND 布局去耦电容，减小噪声对驱动稳定性的影响。
- 升压回路：若使用内部升压功能，注意外部电感、电容的选型与布局，遵循供应商应用指南以保证效率与电磁兼容。
- 散热与封装：LQFP-100 封装需关注焊盘与散热路径，长时间高亮工作时评估结温。
- 接口保护：对 I²C 总线与三线接口增加电气保护（TVS、限流等）以提高可靠性。
- 偏压与亮度：根据显示内容与功耗要求选择合适偏压比，并通过 PWM 或扫描频率进行亮度与闪烁优化。
HT16H25-100LQFP 以其高集成、低功耗与多样化接口，适合需要驱动大规模 LED 阵列且对空间与 BOM 成本敏感的设计。请结合 HOLTEK 官方数据手册进行详细电气参数、时序和典型电路的核对与验证。

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.
