4221 is a 2-channel Hot Swap
TM
 controller that
allows a board to be safely inserted and removed from a
live backplane. Using two independent high side gate
drivers to control two external N-channel pass transistors,
the output voltages can be ramped up with current foldback
to limit the inrush current during the start-up period. No
external compensation capacitors are required at the
GATE pins. The two channels can be configured to ramp up
and down separately or simultaneously for supply volt-
ages ranging from 2.7V to 13.5V and 1V to 13.5V for
channels 1 and 2 respectively.
Each channel has two current limit comparators that
provide dual level and dual speed overcurrent circuit
breaker protection after the start-up period. If any current
sense voltage exceeds 100mV for 1約 or 25mV for the
timeout delay (set by the C
FILTER
 at the FILTER pin), then
the FAULT latch is set and both GATE pins are pulled low.
The FB pins monitor the respective channel output volt-
ages and provide the inputs for the PWRGD comparators
as well as overvoltage protection.
