LTC4231HUD-2#PBF, Hot Swap Controller 1-CH 36V N-Channel Positive Low Voltage Automotive 12-Pin QFN EP Tube /Код si-403373

LTC4231 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. The LTC4231 provides a debounce delay and allows the GATE to be ramped up at an adjustable rate. After start-up, the LTC4231's quiescent current drops to 4µA during normal operation with output active. UVL, UVH, OV and GNDSW monitor overvoltage and under voltage periodically, keeping total quiescent current low. Pulling active low SHDN low shuts down the LTC4231 and quiescent current drops to 0.3µA. During an overcurrent fault, the LTC4231 actively limits current while running an adjustable timer. Typical applications include battery powered equipment, solar powered systems, portable instruments and energy harvesting. • Automatically reapplies power after a cool-down period• Wide operating voltage range from 2.7V to 36V• Adjustable analogue current limit with circuit breaker• Automatic retry or latch off on current fault• Controls single or back-to-back N-channel MOSFETs• 12-lead (3mm ? 3mm) plastic QFN package• Temperature range from -40°C to 125°C
