KTA1136 Image

The KTA1136 from Kinetic Technologies is an IEEE 802.3af-Compliant Power-Over-Ethernet (PoE) IC that has been designed for 13 W PoE-powered devices. It requires an input voltage of 37 - 57 V. This PoE consists of a DC-DC controller circuit, robust 150 V switching power MOSFET, 100 V hot-swap FET and an input protection circuit. It implements all the physical layer-powered device (PD) functionalities as required by the IEEE 802.3af 2003 standard and also supports Type 1 operation for both IEEE 802.3at-2009 and IEEE 802.bt-2018 standards. This PoE IC has been optimized in design to address both electromagnetic (EM) emission concerns as well as surge/over-voltage protection in PoE applications. It contains built-in features that minimize transmission of the system’s common-mode noise into the Unshielded Twisted Pair (UTP) cable.

This PoE controller IC directly implements a surge protection circuit on-chip that enables faster response to surge events and limits stray currents from passing through sensitive circuits such as the Ethernet PHY. It includes under-voltage lockout (UVLO) protection, PD detection, and classification, and hot-swap FET integration protection functions to prevent false triggers or short-circuit-related damages. This IC also offers low-impedance paths to the Earth's ground to allow smooth discharge, thereby resulting in superior reliability and circuit protection. It is available in a surface-mount package that measures 4 x 4 mm and is ideal for point-of-sale (POS) terminals, RFID terminals, thin clients, voice-over-IP (VoIP) phones, pan, tilt, and zoom (PTZ), security and web cameras, WLAN access points, biometric authentication, and IoT applications.
