TPS22916BYFPR 是德州仪器(TI)推出的一款单通道负载开关,旨在为便携设备和电源管理系统提供低损耗、低漏电的电源断接方案。器件支持工作电压范围 1V 至 5.5V,最大连续导通电流 2A,典型导通电阻 60mΩ,关闭状态漏电流极低(10 nA),工作温度范围为 -40℃ 到 +85℃。封装为超小型 DSBGA-4(0.7 × 0.7 mm),适合集成度高、空间受限的应用。
该器件为低 Rds(on) 的 P/N 通道 MOSFET 负载开关(单通道),通过控制引脚输入高电平实现输出导通,低电平则断开输出。低导通电阻保证在通电状态下对系统供电的压降低,极低的关断漏电流使其在待机或断电状态下对电池消耗极小。典型应用包括片上电源门控、外设供电断开、功耗域管理等。
DSBGA-4 超小封装便于高密度布局,但散热能力依赖 PCB 设计。建议:
总结:TPS22916BYFPR 以其低导通电阻、极低漏电流与宽电压兼容性,适合对功耗与体积有严格要求的电源管理场景。合理的 PCB 散热与布局、注意启动瞬态及焊接工艺,可确保器件在系统中可靠工作。

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.
