L9110SM/TR 产品概述

一、产品概况

L9110SM/TR 是华冠(HGSEMI)推出的一款面向小型直流电机和双相步进电机驱动的高集成度芯片,封装为 SOP-8。芯片内部集成低阻抗功率 FET,便于直接驱动小型马达,适用于电池供电与便携式设备场景。器件工作电压范围宽(2.3V~12V),支持典型的微型马达电源需求,同时体积小、易于 PCB 布局。

二、主要电气参数

  • 工作电压:2.3V ~ 12V
  • 静态电流(Iq):约 100 nA(极低静态功耗,适合电池供电)
  • 输出电流(持续):800 mA(单通道典型驱动能力)
  • 峰值电流:1.5 A(短时冲击或启动电流承受能力)
  • 工作温度:-20 ℃ ~ +80 ℃
  • 封装:SOP-8(便于通用 PCB 安装)
  • 集成 FET:是(内部功率 FET 降低外部器件需求)

三、核心特性与优势

  1. 低静态功耗:100 nA 级静态电流显著延长电池供电系统待机时间。
  2. 宽电压支持:2.3V 起即可工作,兼容常见单节锂电池及多节电池方案。
  3. 集成 FET:内部功率场效应管降低外部驱动元件数量,简化电路设计。
  4. 良好驱动能力:800 mA 连续输出与 1.5 A 峰值允许驱动常见微型直流电机或步进电机。
  5. 小体积封装:SOP-8 有利于空间受限的消费类电子与玩具产品应用。

四、典型应用场景

  • 小型直流电机驱动(玩具车、微型风扇、光驱等)
  • 双相步进电机(微型定位系统、打印机、摄像头云台)
  • 便携式电动工具与电动模型
  • 智能家居与机器人驱动单元
  • 低功耗电池供电产品中的动力驱动模块

五、可靠性与保护

L9110SM/TR 针对驱动场景做了功耗与热管理方面的考量(芯片内部常见保护设计包括短路/过流限制与热关断),配合合理 PCB 设计可保证长期可靠工作。器件在高电流冲击时需注意峰值限制与散热条件,避免持续在峰值电流下工作导致温升过高。

六、设计与使用建议

  1. 电源旁路:在 VCC 与 GND 之间放置 0.1 μF 陶瓷电容并配合 10 μF 左右的电解或固态电容,抑制电机开关噪声与瞬态电压。
  2. 布局走线:功率输出线尽量短、宽,减少压降与发热;将电源回流路径靠近芯片 GND 引脚布局。
  3. 热管理:当驱动接近额定输出电流时,留意芯片温升,必要时增加散热铜箔或散热片。
  4. PWM 控制:使用 PWM 调速时,注意 PWM 频率选择避免造成可听噪声与效率下降,一般几十 kHz 为宜(视电机特性调整)。
  5. 启动冲击:电机启动瞬间电流较大,应保证电源及布线能承受 1.5 A 峰值冲击;若电源能力有限,可考虑限流或软启动方案。
  6. 保护电路:若应用对可靠性要求高,建议在输出端并联适当的瞬态抑制元件与熔断/限流器件以防意外短路或负载异常。

七、小结

L9110SM/TR 以其宽电压、低静态电流与集成 FET 的特点,适合用于对体积、功耗与成本有较高要求的小型电机驱动场合。正确的电源滤波、布线与散热设计能够充分发挥其 800 mA 持续驱动与 1.5 A 峰值能力,为各类便携与嵌入式驱动应用提供稳定、经济的解决方案。如需针对具体电路的引脚说明、典型应用图或详细参数曲线,可进一步提供相应资料与原理图参考。

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.
