TPS2375PWR-1

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

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.

- Pin count: 16 pins (16-pin package)
- Function: PoE PD controller. It handles IEEE 802.3af/at PD detection and classification and provides a gate drive for the external high-side MOSFET to control power delivery. It also monitors VBUS, current/overload, UVLO, faults/status, and supports PD negotiation for power delivery.

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor design and manufacturing company that produces analog, mixed-signal, and embedded processing integrated circuits.

TPS2375PWR-1 is a PoE PD controller. Typical application areas include:
- Endspan and midspan PoE PD interfaces (IEEE 802.3af/at/bt)
- IP cameras and VoIP phones
- Wireless access points
- PoE-powered sensors and industrial IoT devices
- Digital signage and networked audio/video endpoints
- Compact embedded PoE power supplies and power-management solutions
These apps benefit from safe DC power extraction from PoE, with high-voltage handling and protection features.

TPS2375PWR-1 uses an 8-pin VSSOP (Very Small Outline Package).
