25 / 40 page  LTC4211 25 4211fb 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 VCC makes connection, the bases of transistors Q1 and Q2 are pulled high, biasing them ON. When either one of them is ON, the LTC4211’s ON pin is held low, keeping the LTC4211 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 LTC4211’s ON pin low. If the ON pin is held low for more than 8μs, the LTC4211’s GATE pin is switched to ground. Figure 13. Hot Swap Controller On Daughter Board (Staggered Pin Connections) Figure 14.
