Ag9905M

V2.4 April 2020 Datasheet Ag9900 Silvertel Ultra Miniature PoE Module Features IEEE802.3af compliant 1500V isolated DC/DC Converter Ultra Low Profile Tiny SMT (14mm x 21mm X 13mm) or DIL package (14mm x 21mm X 8mm) Low cost Input voltage range 36V to 57V Minimal external components required Short-circuit protection Industrial temperature option available Over temperature protection (Industrial Temperature version- MT or LP) Adjustable Output Silvertel design-in assistance Description The Ag9900 Power-over-Ethernet (PoE) modules are the smallest POE solution in the world and designed to extract power from a conventional twisted pair Category 5 Ethernet cable, conforming to the IEEE 802.3af PoE standard. The Ag9900 signature and control circuit provides the PoE compatibility signature required by the Power Sourcing Equipment (PSE) before applying up to 15W power to the port. The Ag9900 provides a Class 0 signature. The DC/DC converter operates over a wide input voltage range and provides a regulated output. The DC/DC converter also has built-in short-circuit output protection.
