DESCRIPTIO
The LTC
that allows a board to be safely inserted and removed from
a live backplane. An internal high side switch driver
controls the GATE of an external N-channel MOSFET for a
supply voltage ranging from 2.7V to 16.5V. The LTC4210
provides the initial timing cycle and allows the GATE to be
ramped up at an adjustable rate.
The LTC4210 features a fast current limit loop providing
active current limiting together with a circuit breaker
timer. The signal at the ON pin turns the part on and off and
is also used for the reset function.
This part is available in two options: the LTC4210-1 for
automatic retry on overcurrent fault and the LTC4210-2
for latch off on an overcurrent fault.
