1 / 24 page  LTC4216 4216f 1 ■ Allows Safe Board Insertion and Removal from a Live Backplane ■ Controls Load Voltages from 0V to 6V ■ Fast Response Limits Peak Fault Current ■ Adjustable Analog Current Limit ■ Adjustable Soft-Start with Inrush Current Limiting ■ Adjustable Response Time for Overcurrent Protection ■ Low Circuit Breaker Trip Threshold: 25mV ■ No External Gate Capacitor Required ■ Gate Drive for External N-Channel MOSFET ■ Adjustable Supply Voltage Power-Up Rate ■ ⎯R⎯E⎯S⎯E⎯T and ⎯F⎯A⎯U⎯L⎯T Output ■ 10-Lead MSOP and 12-Lead (4mm × 3mm) DFN Packages Ultralow Voltage Hot Swap Controller The LTC ®4216 is a positive low-voltage Hot SwapTM 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 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 amplifier, an electronic circuit breaker with adjustable response time provides dual level overcurrent protection. No external gate capacitor is required for the analog cur- rent limit loop compensation. The FB pin monitors the output supply voltage and signals the ⎯R⎯E⎯S⎯E⎯T output pin. An ON pin provides on/off control and a ⎯F⎯A⎯U⎯L⎯T pin indicates the fault status. The LTC4216 is available in the 10-lead MSOP and 12-lead (4mm × 3mm) DFN packages.
