Description
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.
Features
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
