TPS22916BYFPR 产品概述

一、产品简介

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。

二、主要特性

  • 工作电压:1.0 V ~ 5.5 V,兼容常见单节/多节电池与系统轨电压。
  • 最大连续电流:2 A,适用于中等功率负载。
  • 导通电阻:约 60 mΩ,导通时功耗低、压降小(在 2 A 时近 120 mV)。
  • 漏电流:关断时典型 10 nA,适合对待机功耗要求严格的电池供电系统。
  • 输入控制:高电平有效,驱动逻辑电平范围与器件工作电压范围一致。
  • 封装:DSBGA-4(0.7×0.7 mm),适合对体积与重量敏感的产品。
  • 温度范围:-40℃ ~ +85℃,满足工业级与消费级多数环境。

三、功能与工作原理

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。

四、典型应用场景

  • 移动设备、可穿戴设备的外设电源控制(传感器、蓝牙模块等)。
  • 电池供电的低功耗终端、数据记录仪与远程传感节点。
  • 系统电源路径选择、分区电源管理与热插拔保护(注意并非专门的热插拔控制器)。
  • 需严格控制待机电流的便携电子产品。

五、封装与散热考虑

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:

  • 在 PCB 布局时为输入/输出铜箔做足面积,必要时通过过孔连接底层散热平面;
  • 输入侧靠近电源端和输出侧靠近负载端放置去耦电容,减小导线寄生与瞬态压降;
  • 考虑在高电流或高环境温度条件下,按连续 2 A 工作对导通损耗(I^2·R)进行热预算并适当降额。

六、使用建议与注意事项

  • 控制引脚为高电平有效,应保证驱动电平在器件允许范围内;若与低电压 MCU 连接,确认逻辑兼容性。
  • 虽然导通电阻较低,但启动瞬态电流(如电容充电)可能导致电压跌落,必要时在开关处限制冲击电流或增加软启动/限流措施。
  • 小型 BGA 封装对焊接与回流工艺敏感,遵循 TI 推荐的焊接规范,注意焊盘设计与焊膏量控制。
  • 对于需要更复杂保护(过流限流、快速断开等)的场合,评估是否需外加保护或采用带更多保护功能的器件。

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。

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
