Ultralow Voltage
Hot Swap Controller
The LTC
4216 is a positive low-voltage Hot Swap
TM
controller that allows a board to be safely inserted and
removed from a live backplane. It controls load voltages
ranging from 0V to 6V and isolates a severe fault with
instantaneous analog current limiting.
An internal high side switch driver controls the gate of
an external N-channel MOSFET. An adjustable soft-start
limits the rate of change of the inrush current at start-up
for a large load capacitor. Together with an analog current
limit amplifier, an electronic circuit breaker with adjustable
response time provides dual level overcurrent protection.
No external gate capacitor is required for the analog cur-
rent limit loop compensation.
The FB pin monitors the output supply voltage and signals
the

and a
