概述

Description

TPS23754PWP-1 is Texas Instruments’ PoE PD interface controller for IEEE 802.3af/at. It handles the PD front end (detection, classification, and power negotiation) and controls a high‑voltage switch to draw PoE power from the PSE. The device includes integrated protection (OVP, OCP, SCP, reverse polarity), undervoltage lockout, thermal protection, and fault/status signaling, allowing a compact, few-external-parts PoE front end. It supports Type 1 and Type 2 PDs and operates from the PoE input over a wide voltage range (up to the typical PoE supply voltage). The PWP suffix denotes the package variant for this device. Typical PD applications include IP cameras, VoIP phones, wireless access points, and other PoE-enabled devices. For exact electrical specs, package details, and reference designs, consult TI’s TPS23754 product page and data sheet.

Features

Here are the typical features of TPS23754PWP-1 (IEEE 802.3af/at PoE PD controller in an 8-pin PWP package):
- PoE interface for IEEE 802.3af (PoE) and 802.3at (PoE+) with PD detection, signature, and classification
- Integrated high-voltage switch (MOSFET) for PoE power path
- Wide input range: roughly 30–57 V (PSE to PD range)
- Minimal external components with 8-pin PWP-1 package
- Programmable/current-limited power switch with protection
- Protection features: UVLO, OVP, OCP/short-circuit protection, thermal shutdown
- Fast fault response and soft-start for hot-swap protection
- Disable/enable control and status indication
- Suitable for Type 2 (PoE+) applications and compact PoE PD designs
- Quiescent low standby current
Note: Exact electrical specs (voltage ranges, current limits, and available features) can vary by revision. Please refer to the latest TI datasheet for precise numbers.

Package

TPS23754PWP-1 is in a WSON-8 (8-pin leadless) package.

Pinout

- Pin count: 8 pins (8‑pin package)
- Function: TPS23754PWP‑1 is a PoE PD front‑end controller (IEEE 802.3af/at). It handles PD detection, classification, current limiting, and protection (UV/OV/OC), and it drives the external high-side switch to deliver PoE power to the Powered Device.

Manufacturer

- Manufacturer: Texas Instruments (TI)
- Company type: American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, including power-management ICs, processors, and related devices.

Application

Applications: IEEE 802.3af/at powered devices (PDs). Typical uses include IP phones, wireless access points, network cameras, PoE lighting, industrial IoT sensors and gateways, and other PoE-endpoint products.
