Product Summary

The LTC4211CMS#TR 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 LTC4211CMS#TR provides softstart and inrush current limiting during the start-up period which has a programmable duration. Two on-chip current limit comparators provide dual level overcurrent circuit breaker protection. The slow comparator trips at VCC – 50mV and activates in 20ms (or programmed by an external filter capacitor, MS only). The fast comparator trips at VCC – 150mV and typically responds in 300ns. The applications of the LTC4211CMS#TR are (1)electronic circuit breaker; (2)hot board insertion and removal (either on backplane or on removable card); (3)industrial high side switch/circuit breaker.
