Description
TPS23754PWP-1 is Texas Instruments’ single-port PoE PD interface controller that complies with IEEE 802.3af/at (PoE). It manages PD detection, signature, and classification and controls the PD power path with protection features.
Key points:
- Functions: PoE detection/signature, classification, current-limit control, and fault protection (OV/UV, overcurrent, thermal).
- Power path: Drives or interfaces with the PD power path (external MOSFET or integrated option depending on package/pinout).
- Input range: Designed to operate from the PoE input range (high-voltage, up to the typical PoE rails).
- Protection: Fast fault response and robust protection for reliable PD operation.
- Package: PWP-1, TI’s small, low-profile package variant.
- Applications: PoE-powered devices such as IP cameras, VoIP phones, wireless access points, and other PoE-enabled endpoints.
For exact electrical specs, recommended external components, and application circuits, refer to the TPS23754PWP-1 datasheet.
