Description：

The RT76812 signature and control circuit provides the PoE compatibility signature and

power classification required by the Power Sourcing Equipment (PSE) before applying up

to 36W power to the port. It has been designed to work with existing high power PSE’s from leading manufacturers.

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.

  • Power Classification

• The RT76812 is Type 4 - Class 8 PD requesting the highest nominal amount of power from an IEEE802.3bt PSE  If the RT76812 is connected to an IEEE802.3at PSE, the PSE will recognise the initial Class 4 pulse from the as a Type 2 PD and provide ~25W.

  • PD Signature

  The RT76812 input complies with the IEEE802.3af specification. When the inputs are connected to a Power Sourcing Equipment (PSE), they will automatically present a Powered Device (PD) signature to the PSE (when requested). The equipment will then recognise that a PD is connected to that line and supply power.

  • Operating Temperature Range

  It is important to remember that RT76812 is a power supply, and as such careful consideration should be taken over the mechanical design of the host product, with provision for heat sinking and/or forced air cooling.

  At full power the RT76812 will generate heat. The device has been designed to be used with heatsink plate or thermally connected to the chassis of the host equipment, or cooled with forced air.
