Voltage should not be externally applied to CLASS and ILIM.
V(VDD) = 48 V, R(DET) = 24.9 k, R(CLASS) = 255 , R(ILIM) = 178 k, and –40°C ≤ TJ ≤ 125°C, unless otherwise noted. Positive
currents are into pins. Typical values are at 25
°C. All voltages are with respect to VSS unless otherwise noted.

(1)
Classification is tested with exact resistor values. A 1% tolerance classification resistor ensures compliance with IEEE 802.3af limits.
(2)
This parameter specifies the RTN current value, as a percentage of the steady state inrush current, below which it must fall to make PG
assert (open-drain).
