• Manufacturer: Maxim Integrated Products, Inc.

-48V Hot-Swap Controller with V
No R
ELECTRICAL CHARACTERISTICS (continued)
(V
= -40°C to +85°C, unless otherwise noted. Typical values are at V
Note 1: All currents into pins are positive and all currents out of pins are negative. All voltages referenced to V
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: V
Note 4: Delay time from a valid on condition until the load-probe test begins.
Note 5: The short-circuit threshold is V
Note 6: The time when PGOOD condition is met until PGOOD signal is asserted.
(V
unless otherwise noted.)
