GENERAL DESCRIPTION
APPLICATIONS
include Voice over IP (VoIP) Phones, Wireless LAN Access Point, Security and Web Cameras, Analog Telephone Adapters (ATA) and Point of Sales Terminals. This high level of integration provides significant reliability and protection advantages. The AS1113 integrates rectification and protection circuitry, a PD controller, and a DC-DC converter. This high level of integration provides faster ressponse to surge events and limits stray surge current from passing through sensitive circuits, such as the Ethernet PHY device. The device is designed to provide a safe low impedance discharge paths directly back to the earth ground, resulting in superior reliability and circuit protection. AS1113 has been architected and designed to address both EMI emission concerns and surge/over-voltage protection in POE applications. The device implements many design features that minimizes transmission of system common-mode noise on to the UTP cable. By using high-volume standard CMOS technology, Akros enables its customers to implement higher performance PoE devices with low cost and a small footprint.
