The LTC
廬
4212 is a Hot Swap
TM
controller 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 supply voltages
ranging from 2.5V to 16.5V. The LTC4212 provides soft-
start and inrush current limiting during the start-up
period. It features a power-up timeout circuit that discon-
nects the system supply when the onboard supplies do not
enter into regulation within an adjustable timeout period.
The controller interfaces with external supply monitor ICs
or directly with the PGOOD pin of a DC/DC converter. After
normal power-up, a programmable power good glitch
filter can be enabled to filter out short term dips in the
supplies.
Two current limit comparators provide dual level
overcurrent circuit breaker protection. The slow com-
parator trips at V
CC
鈥?50mV and activates in 18碌s. The fast
comparator trips at V
CC
鈥?150mV and typically responds
in 500ns.
The LTC4212 can be configured for both latchoff and
autoretry applications and is available in a 10-pin MSOP
package.
