Description
The Ag9900 Power-over-Ethernet (PoE) modules are the smallest POE solution in theworld and designed to extract power from a conventional twisted pair Category 5 Ethernetcable, conforming to the IEEE 802.3af PoE standard.The Ag9900 signature and control circuit provides the PoE compatibility signature requiredby 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 regulatedoutput. The DC/DC converter also has built-in short-circuit output protection.
Features
- Ultra Low Profile
- Tiny SMT (14mm x 21mm X 13mm) or DIL package (14mm x 21mm X 8mm)
- IEEE802.3af compliant
- Low cost
- Input voltage range 36V to 57V
- Minimal external components required
- Short-circuit protection
- Industrial temperature version available
- Over temperature protection
- Industrial Temperature version- MT or LP
- Adjustable Output
- 1500V isolation (input to output)
Typical applications
- PoE Related Application
