HT16C23A-64LQFP-7×7 产品概述

一、概要

HT16C23A 是 HOLTEK(台湾合泰/盛群)系列的多段式显示驱动器,采用 LQFP-64(7×7 mm)封装,面向需要低功耗、简单总线控制和升压显示驱动的应用场景。器件集成升压电路与内置振荡器,支持 I²C 接口,能够在 2.4V~5.5V 宽电压范围下稳定工作,适合电池供电或单电源系统。

二、主要特性

  • 支持 I²C 串行通讯接口,便于与 MCU 集成和系统扩展。
  • 内置升压电路,可直接驱动多段显示,无需外接高压源。
  • 内置振荡器,简化系统时钟设计,默认工作频率 32 kHz。
  • 极低静态/工作电流,典型值约 25 μA,利于低功耗应用。
  • 多档偏压与占空比选择:偏压 1/4、1/3;占空比 1/8、1/4,提供亮度与功耗的平衡调节。
  • 工作温度范围宽:-40℃ 至 +85℃,适用于工业级环境。

三、电气参数与工作条件

  • 工作电压:2.4 V ~ 5.5 V,支持常见电池与单电源方案。
  • 工作频率:32 kHz(内置振荡器)。
  • 工作电流:约 25 μA(低功耗设计,实际值视bias/占空比及显示负载而异)。
  • 偏压选择:1/4、1/3,影响 LED 驱动电压与亮度。
  • 占空比:1/8、1/4,可用于亮度控制与散热管理。
  • 环境温度:-40℃ ~ +85℃,适合户外与工业设备。

四、显示配置与驱动能力

HT16C23A 支持多种显示矩阵/段位配置:

  • 段式配置:56 段或 52 段(依据选型与引脚映射)。
  • 位/字节配置:52×8 bit 或 56×4 bit,两种映射方式可满足不同的段列组合需求。
    通过内部升压与多路驱动,可直接驱动较多段数的 LED/7‑segment 显示器,适合信息量较大的面板显示。

五、典型应用场景

  • 电子钟表、计时器与消费类电子显示面板。
  • 仪表盘、便携测试设备与家用电器的数码显示。
  • 工业控制器与楼宇自动化设备中需要多段显示的场合。
  • 低功耗或电池供电设备,需延长待机与运行时间的产品。

六、设计与调试建议

  • 建议在 VCC 旁放置适当的去耦电容,抑制升压开关噪声。
  • 根据显示亮度与电源能力选择合适的偏压与占空比组合,偏压越低、电流需求越小但亮度受限。
  • 使用 I²C 总线时注意上拉电阻选择与总线地址规划,避免与其它从器件冲突。
  • 在高段数与高占空比组合下关注器件发热与PCB散热路径,保证长期稳定性。

七、封装与可靠性

器件采用 LQFP‑64(7×7 mm)封装,便于贴片生产与散热处理。工作温度与低功耗特性保证了在严苛环境中的可靠性。根据应用环境建议进行基板设计与器件布局,确保升压模块周围有足够的布局空间和地平面以降低辐射与干扰。

结语:HT16C23A‑64LQFP‑7×7 以其集成升压、低功耗与灵活的显示配置,适合各类需要多段驱动且重视功耗与系统简化的显示应用。选择时应结合目标面板类型、亮度需求与系统电源特性进行参数匹配与布局优化。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
