DESCRIPTIO
BOARD PHOTOS
Demonstration circuit DC116 is a protected, triple-output
Hot Swap
PC board to be safely inserted into and removed from a live
backplane without disturbing the system power or damag-
ing the connector pins due to high inrush currents. A
programmable electronic circuit breaker protects against
shorts.
Also included on the demo board are LEDs that indicate
whether the circuit breaker has tripped, a power failure has
occurred or the switches are turned off. A push-button
switch is provided for users to generate a system reset and
cycle the outputs. Dip switches allow the trip levels of the
output voltage monitoring circuitry to be changed.

The complete demo includes two separate boards,
DC116A and DC116B. The DC116B is used to simulate the
system backplane with three supply inputs. All the inputs
are bypassed with large capacitors. The DC116A is the
daughter board to be inserted into and removed from the
system power bus. The LTC
nents are placed on this board. A staggered-pin connector
is used to ensure proper connection sequencing.
The applications for DC116 include any system with a data
bus and multiple power supplies that needs to be inserted
into or removed from a live system backplane.
