Description
TPS2384PAP is a Texas Instruments PoE PD controller IC. It handles the front-end function for IEEE 802.3af/at powered devices, managing detection, classification, and power negotiation, and it drives an external MOSFET to connect/disconnect the PD from the Ethernet cable. Key roles include energy-efficient power-path control, current limiting, soft-start, inrush control, and protection against faults such as short circuits, overvoltage, undervoltage, and thermal issues. It is used to implement PoE-powered devices like IP cameras, wireless access points, VoIP phones, and other networked endpoints. The “PAP” suffix denotes a specific TI package variant (package type) and does not affect core functionality; refer to the datasheet for exact pinout, electrical specs, and thermal characteristics.

Features
TPS2384PAP is a PoE front-end interface controller from TI. Key features include:
- IEEE 802.3af/at PD front-end: supports detection, classification and signature per PoE standards (Type 1/Type 2).
- Integrated high-side power MOSFET for the PD path, reducing external components.
- Wide input range within the PoE window (up to about 57 V) to accommodate PD supply.
- Protection: overcurrent/short-circuit with current limit; overvoltage, reverse polarity; thermal shutdown; inrush current limiting.
- Powering options: supports 2-pair and 4-pair PoE configurations; auto-recovery fault protection.
- Low quiescent current and fault/status signaling for system monitoring.
- Small PAP package option for compact board layout.
