ADM1192
When the output of the SETV comparator asserts, this tells the
ALERT block to begin charging the external TIMER capacitor
with a 60 μA charging current. When the voltage on the TIMER
capacitor reaches 1 V the charging cycle is complete. The ALERT
output then asserts (goes high). Different values of TIMER
capacitor generate different time delays between current faults
occurring and the ALERT output asserting. When using the
ALERT output to implement a hot swap circuit, the TIMER
capacitor should be chosen to generate a large enough startup
delay to allow the maximum inrush current to completely
charge up the load without tripping an ALERT fault.

KELVIN SENSE RESISTOR CONNECTION
When using a low value sense resistor for high current measure-
ment, the problem of parasitic series resistance can arise. The
lead resistance can be a substantial fraction of the rated resistance,
making the total resistance a function of lead length.
This problem can be avoided by using a Kelvin sense connection.
This type of connection separates the current path through the
resistor and the voltage drop across the resistor. Figure 30 shows
the correct way to connect the sense resistor between the VCC
pin and the SENSE pin of the ADM1192.
