The LTC9105ATP is an IEEE 802.3af/at/bt (" PoE 2 ") Power over Ethernet (PoE) Receiving Device (PD) controller with input current, voltage and power telemetry functions. The LTC9105ATP includes an I2C interface for reading telemetry data, the power allocated by the power supply equipment (PSE), and the auxiliary input status, as well as writing the power input priority. The LTC9105ATP also features a configurable downstream power-on disabling function. When the power allocated by the PSE is lower than the power requested by the PD, it will issue a power shortage indicator.
