4 / 23 page -48V Hot-Swap Controllers with VIN Step Immunity and No RSENSE 4 _______________________________________________________________________________________ Note 1: All currents into pins are positive and all currents out of pins are negative. All voltages referenced to VEE, unless otherwise specified. Note 2: All limits are 100% tested at +25°C and +85°C. Limits at -40°C and -10°C are guaranteed by characterization. Note 3: Delay time from a valid on-condition until the load probe test begins. Note 4: VEE or UVLO voltages below VUVLO,F or VUVLO_REF,F, respectively, are ignored during this time. Note 5: The time (VOUT - VEE) > VSC + overdrive until (VGATE - VEE) drops to approximately 90% of its initial high value. Note 6: The time when the PGOOD (PGOOD) condition is met until the PGOOD (PGOOD) signal is asserted. ELECTRICAL CHARACTERISTICS (continued) (VEE = -10V to -80V, VIN = GND - VEE, VSTEP_MON =VEE, RLP = 200 Ω, UVLO open, TA = -40°C to +85°C, unless otherwise noted. Typical values are at VEE = -48V, TA = +25°C.)
