LTC4212

Hot Swap Controller with

Power-Up Timeout

DESCRIPTIO

FEATURES

The LTC^®4212 is a Hot Swap^TMcontroller that allows a

board to be safely inserted and removed from a live

backplane.Aninternalhighsideswitchdrivercontrolsthe

gateofanexternalN-channelMOSFETforsupplyvoltages

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-

nectsthesystemsupplywhentheonboardsuppliesdonot

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.

MS10 Package

Two current limit comparators provide dual level

overcurrent circuit breaker protection. The slow com-

paratortripsatV_CC–50mVandactivatesin18µs. Thefast

comparator trips at V_CC– 150mV and typically responds

in 500ns.
