DESIGN FEATURES Hot Swap Controller with
Power-Up Timeout Function
Simplifies Hot Swapping Boards
with Multiple Power Supplies
by Anthony Ng and YK Sim Introduction
The LTC4212 is a Hot Swap controller that allows safe board insertion
and removal from a live backplane.
It features a supply range of 2.5V to
16.5V, programmable soft-start with
inrush current limiting, automatic retry or latched mode operation, a high
side drive for an external N-channel
MOSFET and dual level overcurrent
fault protection.
Unlike many Hot Swap controllers,
the LTC4212 does not monitor the load
side of the MOSFET directly. Instead,
the LTC4212 interfaces with external
power supply monitor ICs or directly
with the PGOOD pin of a switching
regulator. This permits the LTC4212 to
monitor any number of supplies on the
board. It has a power-up timeout function that disconnects a card from the
backplane supply when the monitored …

DESIGN IDEAS Ramp Three Supplies with a Supply
Monitor and Hot Swap Controller
by Mitchell Lee
Many digital systems with multiple
supply voltages require simultaneous
ramping of supplies at power up. Since
the power supply usually consists of
separate regulators for each voltage,
it is impossible to guarantee simultaneity of output. The circuit shown in
Figure 1 ramps the outputs of three
supplies and ensures tracking at
power up and during recovery from a
fault.
Regulators invariably start up at
different rates and different times
based on current capability, filter
capacitance and loop characteristics,
so there are no guarantees as to how
or when the outputs will rise to their
respective voltages. In this case, an
LTC1728-2.5 triple supply monitor
keeps watch over each of three regulated supplies (1.8V, 2.5V and 3.3V).
