APPLICATIONS INFORMATION

Hot Circuit Insertion
When a circuit board is inserted into a live PCI slot, the
supply bypass capacitors on the board can draw huge
transient currents from the PCI power bus as they charge
up. The transient currents can cause permanent damage
to the connector pins and cause glitches on the power bus,
causing other boards in the system to reset.
The LTC1643A is designed to turn a board’s supply
voltages on and off in a controlled manner, allowing the
board to be safely inserted or removed from a live PCI slot
without glitching the system power supplies. The chip
also protects the PCI supplies from shorts and monitors
the supply voltages.
The LTC1643AH is designed for motherboard applica-
tions, while the LTC1643AL/LTC1643AL-1 are designed
for CompactPCI applications where the chip resides on
the plug-in board.
VEEOUT (Pin 15): –12V Supply Output. A 1.2 switch is
connected between VEEIN and VEEOUT. VEEOUT must
exceed –10.8V before the PWRGD signal can go high on
the LTC1643AH and LTC1643AL.
PIN FUNCTIONS

12VOUT (Pin 16): 12V Supply Output. A 0.5 switch is
connected between 12VIN and 12VOUT. 12VOUT must
exceed 11.4V before the PWRGD signal can go high on the
LTC1643AH and LTC1643AL.
