概述

Description

TPS2375PWR‑1 is TI’s PoE (Power over Ethernet) Powered Device (PD) controller from the TPS2375 family. It handles the PD-side interface to a PoE PSE, performing detection, classification, and power negotiation, while providing a controlled, current-limited path to the load via an external high-side switch and protection features (OC/short-circuit, UVLO, thermal). The PWR‑1 suffix indicates a PowerPAD/thermally enhanced package variant for compact, thermally driven designs. Typical applications include PoE-powered devices such as IP cameras, VoIP phones, wireless access points, and other PoE PDs. For exact electrical specs (detection/classification thresholds, current limit, startup behavior) and evaluation kits, refer to the TPS2375PWR‑1 datasheet and TI PoE design resources. If you need a quick comparison or a recommended design approach, I can summarize that too.

Package

PowerPAD thermally enhanced package (16-pin) with an exposed pad.

Pinout

Pin count: 8 pins (PowerPAD variant; bottom pad used for thermal/ground).
Main function: PoE IEEE 802.3af/at PD controller with integrated FET (PD switch).
Pin functions (typical):
- DRAIN: Drain of the integrated FET; connects to the PD input line.
- SOURCE: Source of the integrated FET; connects to the PD output/side.
- VIN: Supply for the controller logic.
- GND: Ground.
- EN (Enable): Enables/disables the controller.
- ISENSE: Current-sense input for overcurrent protection.
- RTN: Return/reference for the PD interface (signal return).
- VREF (or VFB): Reference/feedback for thresholds.
Note: exact pin names can vary by package revision; refer to the TPS2375PWR datasheet for precise pinout.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits and related electronics components.

Application

TPS2375PWR-1 is a PoE PD front-end controller (IEEE 802.3af/at). Typical applications include:
- IP cameras, VoIP phones, wireless access points
- PoE-enabled displays and lighting fixtures
- Industrial sensors and remote monitoring devices
- Embedded PoE PDs in network switches and edge routers
- Other PoE-powered devices requiring robust PD interface with detection, classification, current limit, OVP, and short-circuit protection.
