The LTC4221 is a 2-channel Hot Swap™ controller that allows a board to be safely inserted and removed from a live backplane. Using two independent high side gate drivers to control two external N-channel pass transistors, the output voltages can be ramped up with current foldback to limit the inrush current during the start-up period. No external compensation capacitors are required at the GATE pins. The two channels can be configured to ramp up and down separately or simultaneously for supply voltages ranging from 2.7V to 13.5V and 1V to 13.5V for channels 1 and 2 respectively.Each channel has two current limit comparators that provide dual level and dual speed overcurrent circuit breaker protection after the start-up period. If any current sense voltage exceeds 100mV for 1µs or 25mV for the timeout delay (set by the CFILTER at the FILTER pin), then the FAULT latch is set and both GATE pins are pulled low.The FB pins monitor the respective channel output voltages and provide the inputs for the PWRGD comparators as well as overvoltage protection.Applications Electronic Circuit Breaker Power Supply Sequencing Live Board Insertion and Removal Industrial High Side Switch/Circuit Breaker
