Description
TPS2375PWR-1 is TI’s PoE PD interface reference design built around the TPS2375 controller. It provides a complete PD front end that negotiates with a PoE PSE under IEEE 802.3af/at and controls the PoE power path to the powered device.
Key points:
- PoE detection, classification, and power-path control
- Protection features: UVLO, OVP, overcurrent, short-circuit, thermal protection; ESD safety
- Accepts standard PoE input (~60 V) and delivers the PD output
- Ready-to-use design with schematics, BOM, layout, and, if available, firmware/resources
Typical uses:
- IP cameras, wireless access points, VoIP phones, and other PoE-powered devices
What you get:
- A plug‑and‑play reference design to shorten development and serve as a production-start point
Where to find:
- TI product page for TPS2375PWR-1; EVMs, user guides, BOMs, and design files are available there.

Features
TPS2375PWR-1 Features (concise)
- IEEE 802.3af/at PoE PD interface controller with integrated high‑voltage switch (FET) for simplified PD front end
- PoE input range suitable for Type 1/Type 2 operation (up to the standard PoE rectified input voltage)
- Signature detection, classification, and power negotiation per PoE requirements
- Robust protection: overcurrent/short-circuit, overvoltage, undervoltage lockout (UVLO), and thermal shutdown
- Soft-start and controlled inrush for gentle power-up
- Hot‑swap friendly with low quiescent current in standby
- Compact, RoHS-compliant package suitable for isolated PD designs
- Designed to drive downstream DC‑DC converters in PoE applications
Note: Always refer to the official TI datasheet for exact electrical specs and recommended operating conditions.
