V1.1 April 2019 Datasheet Ag6800 Silvertel IEEE802.3bt PSE Module 1. Features PbPb Type 4 PSE Compliant with IEEE802.3bt Backward compatible to IEEE802.3at Type 1(af) & Type 2 Small DIL package size 51mm (L) x 35mm (W) x 7mm (H) High Efficiency (99%) Low cost Output power up to 97W Minimal (low cost) external components required Over-current and short circuit protection Silvertel design-in assistance 2. Description The Ag6800 is an IEEE802.3bt compliant Power Sourcing Equipment (PSE) module which is also designed to be used with lower power IEEE802.3af, IEEE802.3at power devices and compatible with legacy protocols such as PoH and UPoE. The Ag6800 is a complete, easy to implement solution for adding POE functionality to a wide variety of applications requiring higher power up to 97W such as lighting systems, digital signage, Point-of-Sale systems, LCD TVs, computer monitors and video projectors. Ag6800 is a self-contained module, requiring just a few external components to provide the complete control and feedback to the Powered Device (PD) that is connected to the PSE.
