Working Principles

The MAX5953AUTM+T is a Power-over-Ethernet (PoE) controller that enables the transmission of both data and power over a single Ethernet cable. It integrates a DC-DC converter, which efficiently converts the input voltage from the Ethernet cable to the desired output voltage. The programmable current limit ensures that the power delivered to the connected device remains within safe limits. In case of excessive temperature, the thermal shutdown feature protects the device from damage.
