概述

Description

TPS2546QRTERQ1 is an automotive-qualified high-side load switch from Texas Instruments. It provides controlled power delivery to a single load by integrating a power MOSFET with protection and control features.
Key points:
- Integrated MOSFET, current-limit/overcurrent protection, and overtemperature protection
- Reverse-current blocking and fault/status indication
- Enable input and soft-start to reduce inrush
- Suitable for 2.7–5.5 V systems (USB ports, sensors, battery chargers, etc.)
- Q1 suffix denotes automotive (AEC-Q100) qualification
This device simplifies power-switching design in automotive and rugged electronics, combining protection, control, and low BOM in a compact package. For exact electrical specs, pinout, and behavior, consult the TPS2546 datasheet.

Features

TPS2546QRTERQ1 is a TI USB port power switch. Key features:
- Single high-side switch with current limit and fault protection
- Programmable current limit via external ISET resistor
- Overcurrent/short-circuit protection with thermal shutdown
- Overvoltage protection
- Undervoltage lockout
- Enable input to turn output ON/OFF
- Status/FAULT reporting pins
- Reverse-current protection
- Low quiescent current
- Small RoHS-compliant QFN package (QR suffix)
- Suitable for USB port protection, battery charging, and general power-management applications

Package

TPS2546QRTERQ1 comes in an 8-pin VSSOP package (VSSOP-8), and is a Tape-and-Reel (R) version.

Pinout

- Pin count: 16 pins (VQFN-16/16-pin package).
- Function: Automotive-grade single-channel USB VBUS high-side power switch with programmable current limit and protection (overcurrent/short-circuit, undervoltage/overtemperature, reverse current) and enable/diagnostic control to switch VBUS on/off.

Manufacturer

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

Application

TPS2546QRTERQ1 is an automotive-grade high-side power distribution switch with current limiting and fault protection. Typical application areas:
- Automotive: power distribution for ECUs, actuators, lighting, infotainment
- Industrial/embedded control: load switch with current limit and fault protection
- Consumer electronics: USB/charging ports, docking stations
- Battery-powered devices: hot-swap and current limiting
- Any system needing controlled power sequencing and protection.
