The LTC4216 is a positive low-voltage Hot Swap TM controller that allows a board to be safely inserted and removed from a live backplane. It controls load voltages ranging from 0V to 6V and isolates a severe fault with instantaneous analog current limiting.

An internal high side switch driver of LTC4216 controls the gate of an external N-channel MOSFET. An adjustable soft-start limits the rate of change of the inrush current at start-up for a large load capacitor. Together with an analog current limit amplifi er, an electronic circuit breaker with adjustable response time provides dual level overcurrent protection. No external gate capacitor of LTC4216 is required for the analog cur-rent limit loop compensation.

The FB pin of LTC4216 monitors the output supply voltage and signals the RESET output pin. An ON pin provides on/off control and aFAULT pin indicates the fault status. The LTC4216 is available in the 10-lead MSOP and 12-lead (4mm ×3mm) DFN packages.
