The data in the above table is based on using standard
JEDEC Thermal Conductivity Test Boards based on EIA/
JEDEC standards JESD51-7 and JESD51-3.
System Considerations
A) Continued proper operation of the LM5067 hot swap circuit
requires capacitance be present on the supply side of the
connector into which the hot swap circuit is plugged in, as
depicted in Figure 2. The capacitor in the “Live Backplane”
section is necessary to absorb the transient generated when-
ever the hot swap circuit shuts off the load current. If the
capacitance is not present, inductance in the supply lines will
generate a voltage transient at shut-off which can exceed the
absolute maximum rating of the LM5067, resulting in its de-
struction.
B) If the load powered via the LM5067 hot swap circuit has
inductive characteristics, a diode is required across the
LM5067’s output to provide a recirculating path for the load’s
current. Adding the diode prevents possible damage to the
LM5067 as the OUT pin will be taken above ground by the
inductive load at shutoff. See Figure 18.
