Si3404-GM

Si3404-GM Class 3 15W Power Over Ethernet (PoE) PD Interface Devices

The Si3404-GM is the industry’s most highly-integrated, IEEE 802.3 at Type 1-compliant, PoE PD interface and pulse-width-modulated (PWM) switching regulator. By setting a new bar for device integration, lowest overall BOM cost, efficiency and reliability, the Si3404-GM enables designers to easily add PoE functionality to their Ethernet products. When included in the design of a PoE-enabled system, such as a wireless access point or VoIP phone, the Si3404-GM converts the high voltage (typically ±48 V) supplied over Ethernet copper UTP cabling into a regulated, low-voltage dc supply. In addition, the Si3404-GM combines all the required IEEE 802.3 at Type 1 detection, classification and hot swap interfaces with a complete, high efficiency, PWM switching regulator.
