Overview
The LTC4211IMS#TRPBF, produced by Analog Devices Inc., is a hot swap controller designed to enable safe insertion and removal of boards from a live backplane. This device integrates an internal high side switch driver that controls the gate of an external N-channel MOSFET, supporting supply voltages from 2.5V to 16.5V. It features soft-start and inrush current limiting during the start-up period, which can be programmable. The LTC4211 also includes a glitch filter to protect against spurious reset signals and functions as an electronic circuit breaker, enhancing system reliability and safety.
