5 / 54 page High-Power, Quad, Monolithic, PSE Controllers for Power over Ethernet _______________________________________________________________________________________ 5 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.) (Note 2) PARAMETER SYMBOL CONDITIONS MIN TYP MAX UNITS LOAD DISCONNECT DC Load Disconnect Threshold VDCTH Minimum VSENSE_ allowed before disconnect (DC disconnect active), VOUT_ = 0V 2.5 3.75 5.0 mV AC Load Disconnect Threshold IACTH Current into DET_, for I < IACTH the port powers off, ACD_EN_ bit = H; VOSC = 2.2V, MAX5965B (Note 6) 285 320 360 μA Oscillator Buffer Gain AOSC VDET_/VOSC, ACD_EN_ bit = H, MAX5965B 2.9 3.0 3.1 V/V OSC Fail Threshold VOSC_FAIL Port does not power on if VOSC < VOSC_FAIL and ACD_EN_ bit is high, MAX5965B (Note 7) 1.8 2.2 V OSC Input Impedance ZOSC OSC input impedance when all the ACD_EN_ are active, MAX5965B 100 k Ω Load Disconnect Timer tDISC Time from VSENSE_ < VDCTH to gate shutdown (Note 8) 300 400 ms DETECTION Detection Probe Voltage (First Phase) VDPH1 VAGND - VDET_ during the first detection phase 3.8 4 4.2 V Detection Probe Voltage (Second Phase) VDPH2 VAGND - VDET_ during the second detection phase 9.0 9.3 9.6 V Current-Limit Protection IDLIM VDET_ = VAGND, during detection, measure current through DET_ 1.5 1.8 2.2 mA Short-Circuit Threshold VDCP If VAGND - VOUT_ < VDCP after the first detection phase a short circuit to AGND is detected 1V Open-Circuit Threshold ID_OPEN First point measurement current threshold for open condition 12.5 μA Resistor Detection Window RDOK (Note 9) 19.0 26.5 k Ω Detection rejects lower values 15.2 Resistor Rejection Window RDBAD Detection rejects higher values 32 k Ω |
