TPS2378DDAR PoE PD Interface Chip High Power SOIC-8

The TPS2378DDAR is a specialized IEEE 802.3at-compliant Powered Device (PD) interface chip designed for high-power Power over Ethernet applications. Housed in a compact SOIC-8 package with an integrated thermal pad (PowerPAD), this chip acts as a robust gateway for PoE systems, supporting Type 2 (30W) requirements. It features a low 0.5-ohm internal pass MOSFET to reduce power loss and heat, alongside a programmable inrush current limit to protect the system during startup. The device includes 2-event classification, power-good signaling, and thermal shutdown protection, making it a highly reliable solution for powering IP cameras, Wi-Fi access points, and industrial IoT devices directly through Ethernet cabling.

Features:

• High Power Efficiency: Internal 0.5-ohm pass MOSFET minimizes power dissipation for 30W+ applications.
• IEEE 802.3at Compliant: Fully supports Type 2 hardware classification and power-up sequences.
• Compact SOIC-8 Package: Integrated thermal pad ensures stable operation under high current loads.
• Advanced Protection: Includes programmable inrush current limit and thermal shutdown functionality.
• Easy Identification: Marked with '2378' on the silk screen for simplified component sourcing.
• Versatile Voltage Range: Rated for up to 57V DC input, compatible with standard PoE injectors and switches.
