Description
Ag9900 is now the smallest PoE module in the world, superseding the Ag9800. It is designed such that adding just two diode bridges and an electrolytic capacitor to this truly tiny module is enough to enable PoE functionality in a product. Ag9900 is fully compliant to the IEEE 802.3af PoE standard. It provides a POE signature, classification, isolation and DC to DC conversion options for 12V, 5V, 24V or 3.3V, while taking up minimal PCB space. It is ideal for space constrained PoE applications such as IP phones, wall mount appliances, IP cameras, thermostats, smoke detectors and room sensors, and is perfect for a whole range of new IoT and building automation sensors and devices.
Features
- Ultra-miniature package size and profile
- Cost optimised IEEE802.3af POE
- Overload and short-circuit protection
- 1500V DC impulse test isolation (input to output)
- Integral DC/DC converter
- Integrated Thermal Protection option
