4 / 53 page  High-Power, Quad, Monolithic, PSE Controllers for Power over Ethernet 4 _______________________________________________________________________________________ ELECTRICAL CHARACTERISTICS (continued) (VAGND = 32V to 60V, VEE = 0V, VDD to VDGND = +3.3V, all voltages are referenced to VEE, unless otherwise noted. Typical values are at VAGND = +48V, VDGND = +48V, VDD = (VDGND + 3.3V), TA = +25°C. Currents are positive when entering the pin and negative other- wise.)
