KTA1137A Image

The KTA1137A from Kinetic Technologies is an IEEE 802.3af-Compliant Power-Over-Ethernet IC that has been designed for 30 W PoE-powered devices. It requires an input voltage of 9.5 - 57 V. This IC is a single-chip CMOS solution designed for power-over-ethernet (PoE)-powered devices. It seamlessly integrates input surge protection, a power delivery (PD) controller, and a low-emission DC-DC controller. This PoE complies with IEEE 802.3af-2005 and IEEE 802.3at-2009 standards, encompassing 2-event classification, a Type-2 PSE detection indicator, PD detection, under-voltage lockout (UVLO), and hot-swap FET integration. It effectively mitigates electromagnetic emission issues and enhances surge/over-voltage protection in PoE applications by minimizing common-mode noise transmission on unshielded twisted pair (UTP) cables.

This PoE features on-chip surge protection, offering rapid response to surge events and safeguarding sensitive circuits, such as the Ethernet PHY, ensuring superior reliability and circuit protection. It is available in a surface-mount package that measures 5 x 5 mm and is ideal for pan, tilt, and zoom (PTZ), security and web cameras, voice-over-IP (VoIP) phones, wireless LAN access points, WiMAX terminals, point-of-sale (PoS) terminals, RFID terminals, thin clients and notebook computers and fiber-to-the-home (FTTH) terminal applications.
