TPS2547RTER

TPS2547RTER is a Texas Instruments single‑channel high‑side power-distribution switch used to safely power downstream loads (commonly USB/5V rails). It provides protection and controlled power delivery: current‑limit/OC protection, short‑circuit protection, overvoltage protection, reverse-current blocking, and thermal shutdown. An enable input allows turning the switch on/off, and a status/fault output signals protection events. The current limit is adjustable with an external resistor, and soft‑start helps suppress inrush. The “RTER” suffix typically denotes tape‑and‑reel packaging for automated assembly. Typical applications include USB ports, portable chargers, docking stations, and other devices requiring protected, controlled power to downstream circuitry. For exact electrical specifications, pinout, and recommended configurations, refer to the TI TPS2547 datasheet.

TPS2547RTER features (concise):
- High-side power distribution switch with current limiting and protection
- Input voltage range: 2.7 V to 5.5 V; reverse current protection
- Current limit set by external ILIM resistor (programmable)
- Overcurrent/short-circuit protection and thermal shutdown
- Enable (ON/OFF) control input
- Fault/status indication output for protection events
- Soft-start to limit inrush current
- Low on-state resistance for minimal voltage drop
- Suitable for USB/application power-path use
- Tape-and-Reel (RTER) packaging for automated assembly
Note: exact current-limit values and timing specs are in the TI datasheet; verify for your specific design.

TPS2547RTER is an 8‑pin device (VSSOP‑8/TSSOP‑8). It is a hot‑swap controller with programmable current limit and overcurrent protection for a high‑side power rail, providing soft‑start and fault/status signaling to protect the supply during hot‑plug events.

- Manufacturer: Texas Instruments (TI).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog and embedded processing integrated circuits and related electronics components.

TPS2547RTER is a dual high-side switch with current limit and fault protection. Typical applications:
- USB port power distribution (per-port switching with overcurrent/short-circuit protection) in hubs, docks, and chargers
- Consumer electronics powering multiple rails (tablets, phones, wearables) needing safe power-on sequencing
- Portable/battery-powered devices requiring controlled on/off and load protection
- Automotive and industrial electronics for protected, switchable power rails
- Systems with per-load protection for LEDs, sensors, and peripherals requiring reliable fault containment

TPS2547RTER is in an 8-pin VSON package (3×3 mm).
