GENERAL DESCRIPTION
The ADM1073 is a full-feature, negative voltage, hot swap
controller that allows boards to be safely inserted and removed
from a live −48 V backplane. The part provides precise and
robust current limiting, and protection against both transient
and nontransient short circuits in overvoltage and undervoltage
conditions. The ADM1073 can operate from a negative voltage
of −18 V to −80 V and can tolerate transient voltages of up to
−200 V.
Inrush current is limited to a programmable value by control-
ling the gate drive of an external N-channel FET. The maximum
current limit is set by the choice of the sense resistor, RSENSE.
A built-in soft start function allows control of the inrush
current profile by an external capacitor on the soft start (SS)
pin.
An external capacitor on the TIMER pin determines the time
for which the FET gate is controlled to be high when maximum
inrush current flows. The ADM1073 employs a limited consec-
utive retry scheme, whereby, if the load capacitance is not fully
charged within one attempt, the FET gate is pulled low and
retries after a cooling period.
