APPLICATIONS INFORMATION
A more elaborate connection sense scheme is shown in
Figure 16. The bases of Q1 and Q2 are wired to short pins
located on opposite ends of the edge connector because
the installation/removal of printed circuit cards gener-
ally requires rocking the card back and forth. When V
CC
 
makes connection, the bases of transistors Q1 and Q2
are pulled high, biasing them ON. When either one of
them is ON, the LTC4211s ON pin is held low, keeping
the LTC4211 OFF. When both the short base connector

pins of Q1 and Q2 finally mate to the backplane, their
bases are grounded, biasing the transistors OFF. The
ON pin voltage is then pulled high by R3 enabling the
LTC4211 and a power-up cycle begins.
A software-initiated power-down cycle can be started by
momentarily driving transistor M1 with a logic high signal.
This in turn will drive the LTC4211s ON pin low. If the ON
pin is held low for more than 8約, the LTC4211s GATE
pin is switched to ground.
