HL118 H桥驱动芯片产品概述

HL118是富海微(HL)推出的一款单H桥集成驱动芯片,针对小功率直流负载(如微型电机、电磁阀)设计,以宽电压适配、低静态功耗、高集成度为核心优势,适配便携电子、小型家电、物联网终端等多场景需求。

一、产品定位与核心价值

HL118聚焦“小功率、低功耗、紧凑设计”三大核心,解决传统分立H桥电路体积大、功耗高、焊接复杂的痛点:

  • 集成完整H桥拓扑,无需外部MOS管、续流二极管等分立器件,大幅简化PCB设计;
  • 低静态电流与宽电压范围,适配电池供电的便携设备,延长续航;
  • 峰值3A驱动能力,满足微型负载瞬间启动需求,兼顾效率与稳定性。

二、关键参数与性能优势

2.1 宽电压适配,覆盖主流电源

工作电压范围为1.8V~8.5V,可兼容:

  • 纽扣电池(CR2032,3V)、锂电池(3.7V/4.2V);
  • 干电池(1.5V×2/3/4)、5V USB电源;
    无需额外电源转换电路,适配多类终端设备。

2.2 低静态功耗,延长电池续航

静态电流(Iq)仅100nA(典型值),待机状态下几乎不消耗电池电量——以3V锂电池(容量200mAh)为例,待机1年的电量损耗不足0.08mAh,可忽略不计,特别适合低功耗要求的智能穿戴、物联网传感器等场景。

2.3 高驱动效率,减少发热损耗

  • 峰值输出电流达3A,可驱动0.5W~2W的微型直流电机(如玩具车电机、微型泵),满足瞬间启动(堵转/重载启动)需求;
  • 导通电阻(Rds(on))为500mΩ(每臂典型值),导通损耗低,连续工作时芯片发热可控,无需额外散热片,进一步缩小产品体积。

2.4 单H桥集成,简化系统设计

内置完整H桥电路,仅需少量外部阻容元件即可实现电机正反转控制,减少PCB布线复杂度,降低物料成本与生产难度。

三、封装与引脚特性

HL118采用SOP-8封装(小型鸥翼封装),符合工业标准,具有以下优势:

  • 引脚间距1.27mm,易焊接(手工/回流焊均可),适合批量生产;
  • 封装尺寸(4.9mm×3.9mm×1.5mm)紧凑,可嵌入手表、手环等小型设备内部;
  • 引脚功能清晰(电源VCC、地GND、电机输出OUT1/OUT2、控制输入IN1/IN2、使能EN等),无需复杂接线。

四、典型应用场景

HL118的性能适配多类小功率负载场景,核心应用包括:

  1. 智能穿戴设备:智能手环/手表的震动电机驱动、蓝牙耳机开盖弹起电机;
  2. 小型家电:手持迷你风扇、桌面加湿器的微型泵驱动;
  3. 物联网终端:智能门锁锁舌电机、环境监测仪的微型执行器;
  4. 玩具与模型:遥控玩具车、无人机微型舵机、航模起落架驱动;
  5. 医疗辅助设备:小型血糖监测仪的泵驱动、家用雾化器的微型电机。

五、环境适应性与可靠性

工作温度范围为**-20℃~+60℃**,可满足:

  • 室内常规环境(0℃~40℃);
  • 户外便携场景(冬季-10℃+5℃、夏季+25℃+60℃);
    符合工业级基本可靠性要求,量产产品失效率低,适合长期稳定运行。

HL118通过高集成度与优性能的平衡,为小功率负载驱动提供了“低成本、小体积、低功耗”的解决方案,是便携电子、物联网等领域的优选器件。

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
