DESCRIPTION

The MP8005 is a complete integrated IEEE

802.3af POE compliant Powered Device (PD)

power supply solution. It includes the PD

control function and an isolated/non isolated

synchronous

regulator

controller.

Thermal

protection is built in to accommodate both

transient and/or overload conditions, shutting

the part down and protecting the input source

as well as the output load depending on the

particular fault conditions. Inrush current limiting

is included to slowly charge the input capacitor

without interruption due to die heating, a

problem encountered without the current limit

foldback feature. The desired output voltage is

user programmable through the selection of an

external resistor divider.
