IEEE 802.3af PoE PD with Integrated DC-DC Controller and 13W Power FET Features Brief Description The KTA1136 is a single-chip, highly integrated CMOS Compliant to IEEE Std. 802.3af-2003 solution for 13W Power over Ethernet (PoE) Powered Supports Type 1 operation for IEEE 802.3at- Devices. Applications include Voice over IP (VoIP) 2009 and IEEE 802.3bt-2018 Phones, Wireless LAN Access Point, Security Cameras, Integrated DC-DC Controller with robust 150V, WiMAX Terminals, Point-of-Sales Terminals, RFID 0.7 typ. supporting both isolated and non- Readers, Thin Clients and Notebook computers. isolated applications Low RDS ON Hot-Swap FET, 0.49 typ. The KTA1136 integrates input surge protection, a PD Adjustable switching frequency from 100kHz controller with a 100V hot-swap FET, a DC-DC controller, to 800kHz and a robust 150V switching power MOSFET. The Programmable DC-DC Current Limit KTA1136 implements all the physical layer Powered Integrated Surge Protection for 15kV/8kV Device (PD) functionality, as required by IEEE 802.3af- System level ESD Compliance 2003 standards. This includes PD detection, classification, under-voltage lockout (UVLO), and Exceptional EMI performance Hot-Swap FET integration. The KTA1136 also supports Integrated Short-Circuit Protection Type 1 operation for IEEE 802.3at-2009 and IEEE Over temperature protection 802.3bt-2018. RoHS & Pb Free 4x4 mm, 16 lead TQFN Package The KTA1136 has been architected to address both EM Industrial temperature range (-40C to +85C) emission concerns and surge/over-voltage protection in PoE applications. The chip implements many design features that minimize transmission of system common- Applications mode noise onto the Unshielded Twisted Pair (UTP). On- Pan, tilt and zoom (PTZ), security and web chip integration of surge protection provides faster response to surge events and limits stray surge current cameras from passing through sensitive circuits, such as the Voice over IP (VoIP) phones Ethernet PHY. The device is designed to provide safe, Wireless LAN access points, biometric low-impedance discharge paths directly to the earth authentication ground, resulting in superior reliability and circuit Point-of-sale (POS) terminals, RFID terminals protection.
