TMI6809-293是拓尔微(TMI)推出的低功耗单路电压监控器,核心作用是为电子系统提供精准的上电复位(POR)和掉电复位(BOR)保护,避免因电压波动导致的程序跑飞、数据错误或硬件损坏。其核心价值聚焦于低功耗、宽适配、紧凑设计,尤其适合电池供电设备、工业级场景及小型化产品,解决了同类产品中功耗高、温限窄或封装大的痛点。
TMI6809-293采用SOT-23-3超小封装,尺寸仅2.9mm×1.6mm×1.1mm,占用PCB面积不足常规封装的1/3,完美适配可穿戴设备、IoT终端等小型化产品。
引脚功能极简:
无需额外上拉电阻(推挽输出自带驱动),外围仅需VDD和GND,BOM成本低、布线难度小,适合批量生产。
结合参数优势,该产品主要应用于:
TMI6809-293以低功耗、宽电压/宽温、紧凑封装为核心竞争力,精准的2.93V阈值和240ms复位超时确保系统稳定,是小型化电子系统的理想电压监控方案。作为拓尔微的工业级产品,其性价比在同类中具有明显优势,可满足多种场景的电压保护需求。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
