TMI8113 产品概述
一、产品简介
TMI8113 是拓尔微（TMI）推出的一款低静态电流微功耗电源开关器件，采用 SOT-23-6 小封装，面向便携式与电池供电系统的电源管理场景。器件支持 1.6V 至 7.2V 宽工作电压范围，峰值电流可达 2A，适合做负载开关、软启动或保护电路中的高侧/低侧通断元件。
二、主要性能特点
- 工作电压：1.6V ～ 7.2V，兼容单节锂电、3.3V/5V 等常见电源轨。
- 峰值电流：2A，满足瞬态大电流需求。
- 导通电阻（Rds(on)）：550 mΩ（典型），在中低电流场合有良好效率。
- 静态电流（Iq）：100 nA，极低的待机损耗，适合长待机/低功耗设计。
- 工作温度：-30 ℃ ～ +85 ℃。
- 封装：SOT-23-6，体积小，便于空间受限应用。
三、电气参数解读与设计要点
- Rds(on)=550 mΩ 表明在高电流下会产生明显功耗与发热。理论上 2A 峰值时耗散约为 P = I^2·R ≈ 2.2W（短时允许），因此 2A 为瞬态峰值，应避免长期持续；对连续负载推荐将额定电流控制在 0.3–0.8A 区间，具体取决于 PCB 散热条件。
- 100 nA 的静态电流非常适合电池供电设备，可以最大限度降低待机电耗。
- 宽输入电压允许器件直接工作在常见单节锂电（3.0–4.2V）、3.3V 或 5V 轨，便于系统集成。
四、封装与热管理建议
- SOT-23-6 小封装便于高密度板级布局，但散热能力有限。推荐采用较大的铜箔填充或底层过孔散热以降低结到环境温升。
- 在需要承受较高连续电流时，应进行热仿真或实测，必要时增加外部散热通道或选择导通电阻更低的替代器件。
五、典型应用场景
- 手机与可穿戴设备的电源管理/负载开关；
- 便携式医疗仪器与手持终端的电池保护与电源切换；
- 物联网节点、遥控器等长待机设备的电源隔离与上电控制；
- USB/外设供电序列化、软启动与短路保护（配合外部限流或熔断设计）。
六、选型与替代建议
- 需更低导通损耗或更高持续电流时，建议选择 Rds(on) 更低、封装散热更好的 MOSFET 或高侧开关。
- 若主要关注极低静态电流与小封装，TMI8113 在多数电池供电待机场景具有优势。
七、使用注意事项
- 对于有较大浪涌电流的负载（如电机或大电容冲击），应加限流或软启动电路以防器件过热或损坏。
- 布线时应尽量缩短高电流回路，引入旁路电容靠近器件以抑制电压尖峰并改善瞬态能力。
- 在高温或封装受限环境中，应按厂方数据手册进行热降额设计。
总结：TMI8113 在低静态电流与小封装需求的电源管理场景中具有良好竞争力。设计时需关注导通损耗与散热约束，合理限定连续负载电流，以发挥其低待机、高集成的优势。

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.
