    n 0.3µA Shutdown Current
    n Wide Operating Voltage Range: 2.7V to 36V
    n Reverse Supply Protection to –40V
    n Adjustable Analog Current Limit with Circuit Breaker
    n Automatic Retry or Latchoff on Current Fault
    n Overvoltage and Undervoltage Monitoring
    n Controls Single or Back-to-Back N-Channel MOSFETs
    n 12-Lead MSOP and 3mm × 3mm QFN Packages The LTC®4231 is a micropower Hot Swap™ controller that
    allows safe circuit board insertion and removal from a live
    power supply. An internal high side switch driver controls
    the gate of an external N-channel MOSFET. Back-to-back
    MOSFETs can be used for reverse supply protection down
    to –40V. n Applications n n n Battery Powered Equipment
    Solar Powered Systems
    Portable Instruments
    Automotive Battery Protection
    Energy Harvesting The LTC4231 provides a debounce delay and allows the ...
