Application Information, cont’d.
Application Circuit 7
Using Short Connector Pin
In some systems short connector pins are used to guarantee that
the power pins are fully mated before the hotswap control circuit
is enabled. For these systems the positive (V
) end of the R1,
R2, and R3 resistor divider should be connected to the short pin
(
Application Circuit 7
).
Unfortunately this will also cause some delay in responding to
UV conditions. If this UV delay is not acceptable, then separate
resistor dividers can be provided for OV and UV with a capacitor
connected from OV pin to the V
EE
pin (
Application Circuit 6
).
