Figure 8. Using the TPS2306 with Bus Switches
With outputs disabled, the bus switches provide electrical isolation between the backplane and plug-in card
buses. This is useful for reducing glitches on the system address and data busses during live insertions.
Because of the linear mode detection of the TPS2306, the FAULT output remains asserted throughout the
output voltage ramp period. This pin is not pulled low until a nominal delay after both output supplies have
stabilized at the input voltage levels (see Figure 9). When this occurs, the slot and backplane busses are
connected with a minimal impedance across the bus interface.
