The LTC4252BIMS8-1#TRPBF is an integrated circuit (IC) component that offers an advanced power sourcing equipment (PSE) controller for Power over Ethernet (PoE) applications. It is manufactured by Linear Technology, a prominent provider of high-performance analog integrated circuits.
Key Features:
1. PoE Controller: The LTC4252BIMS8-1#TRPBF serves as a PSE controller, enabling the delivery of power over Ethernet cables. It follows the IEEE 802.3af standard for PoE functionality.
2. Integrated Solution: This IC combines multiple functions required for PoE applications, including a signature detector, classification, and current-limited power MOSFET drive. Consequently, it simplifies system design and reduces component count.
3. Signature Detection: The LTC4252BIMS8-1#TRPBF incorporates an integrated signature detector that can identify the presence of PoE-compatible powered devices (PDs) connected to the Ethernet cable.
4. Classification Support: With its classification capabilities, this IC can determine the power requirements of connected PDs. It uses two classification modes, enabling support for both legacy and 802.3af-compliant PDs.
5. Fault Protection: It offers comprehensive fault protection features, including short-circuit detection and temperature monitoring. These protections ensure the safe operation of the PSE and protect against faults caused by shorted cables or connected devices
