概要

Description

TPS2547RTER is a Texas Instruments USB port power switch (high-side switch) from the TPS2547 family. It provides controlled VBUS switching with built‑in protection: current‑limit, reverse‑current blocking, overcurrent protection, and thermal shutdown, plus fault/status signaling. The device is enabled/disabled via an input (EN) and is designed to protect both USB hosts and downstream devices while allowing software control of VBUS. The “RTER” suffix typically indicates Tape‑and‑Reel packaging for automated assembly. Suitable applications include USB hubs, chargers, and portable devices needing safe, controlled VBUS power distribution.

Features

TPS2547RTER features (concise):
- Dual high-side power switches for 5V rails (USB-ready) with protection on each output.
- Overcurrent/short-circuit protection (hiccup mode) per channel.
- Overvoltage (OVP) and undervoltage (UVLO) protection.
- Thermal shutdown protection.
- Soft-start/inrush current limiting to protect downstream devices.
- Enable control for each channel and fault/status signaling (open-drain/output).
- Reverse current protection for safe power-downs.
- Low quiescent current for efficiency.
- Suitable input range around 2.7–5.5 V (USB-compatible).
- Packaging: Tape-and-reel (RTER) for automated assembly.
Note: This is a high-level summary of typical TPS2547R family capabilities; refer to the datasheet for exact electrical specs and pin behavior.

Package

TPS2547RTER is in an 8‑pin VSSOP (VSSOP‑8) package. It’s RoHS‑compliant and shipped on Tape & Reel.

Pinout

- Pin count: 14 pins (package type referenced by RTER suffix).
- Function: USB port protection switch with hot-swap capability, providing current limiting and overcurrent protection, plus enable and status/fault signaling.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, digital, mixed-signal, and embedded processing integrated circuits and related electronics.

Application

Application areas of TPS2547RTER:
- USB port power distribution for hosts, hubs, and docking stations
- Downstream USB ports in laptops, tablets, and consumer electronics needing current limit and fault protection
- USB chargers and power adapters with inrush/short-circuit protection
- Embedded/industrial equipment and telecom gear with USB interfaces
- Any system requiring a single-channel, protected USB power switch

Equivalent

TPS2547RTER is a USB port power switch with overcurrent protection and current limit. There isn’t a one‑to‑one cross reference. Comparable devices from other vendors exist (e.g., On Semiconductor, Analog Devices, STMicroelectronics, Renesas) marketed as USB port power switches with OC protection and adjustable current limit. For exact substitutes, provide: supply voltage, desired current limit, number of channels, and package. I can then list precise part numbers.
