STMicroelectronics - STMicroelectronics Innovates Integrated Protection ICs Enabling Smaller, Sleeker Power-over-Ethernet Equipment

Power over Ethernet (PoE), or IEEE 802.3at, is the industry accepted enabling accessories such as Voice-over-IP (VoIP) phones, wireless-LAN acceptance points, RFID tag readers, sensors, or cameras to affix into a arrangement after aswell acute a adjacent bank aperture for power. This enhances accessibility and adaptability for end users, and aswell reduces accessories costs, as no alien AC/DC ability adapter is required. In 2008, VDC Research Group predicted that anniversary shipments of PoE-enabled Ethernet switches will access to over 132 actor ports by 2012.

STMicroelectronics (NYSE: STM), a apple baton in aegis ICs, has simplified the architecture of accessories for powering accessories affiliated to an Ethernet arrangement by introducing an chip surge-protection IC that meets Power-over-Ethernet blueprint and protects adjoin high-voltage surges, including electrostatic acquittal (ESD). ST’s PEP01-5841 aegis IC is acclimated in Power Sourcing Equipment (PSE), such as PoE-enabled Ethernet switches or hubs, which drive the defined 48V accumulation assimilate the Ethernet cable.

The PoE power-supply chip in the Ethernet hub or about-face can bear transients on the ability curve of up to 100V. Extra aegis is all-important to anticipate actual top voltage surges, such as ESD or EOS, from damaging the ability supply. Discrete apparatus are usually acclimated to catch surges to a voltage below 121V (when specified), but the PEP01-5841 integrates a 100V anchor aegis accessory and clarification capacitors for up to four PoE outputs in a individual 5 x 6mm component. This simplifies architecture and saves up to 55 percent of pc-board printed-circuit-board space.

The PEP01-5841 is the aboriginal accessory accouterment 1kV billow aegis as defined by IEC 61000-4-5 that aswell has a anchor voltage accordant with the 100V PSE controller. ESD aegis satisfies common standards including IEC 61000-4-2 and MIL-STD-883 Method 3015.

The PEP01-5841 is accessible immediately, in the industry-standard SO-8 package, priced at $0.25 in quantities of 10,000 pieces.

STMicroelectronics is a all-around baton confined barter above the spectrum of electronics applications with avant-garde semiconductor solutions. ST aims to be the acknowledged baton in multimedia aggregation and ability applications leveraging its all-inclusive arrangement of technologies, architecture ability and aggregate of bookish acreage portfolio, cardinal partnerships and accomplishment strength. In 2008, the Company’s net revenues were $9.84 billion. Further advice on ST can be begin at www.st.com
