ADI LTC4226IMS-2#PBF

Контроллер горячей замены2Автоматический повтор, UVLO

Overview

The LTC4212-2IMS is a Hot Swap™ 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 LTC4212-2IMS provides soft-start and inrush current limiting during the start-up period. It features a power-up timeout circuit that disconnects 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.

The LTC4212-2IMS can be configured for both latchoff and autoretry applications and is available in a 10-pin MSOP package.
