LINEAR TECHNOLOGY LTC4231HUD-2#PBF 芯片, 热拔插控制器, 36V, QFN-12
The is a high voltage micropower hot swap controller in 12 pin QFN package. It allows safe circuit board insertion and removal from live power supply. An internal high side switch driver controls gate of an external N channel MOSFET. The back to back MOSFETs can be used for reverse supply protection down to -40V. The LTC4231-2 provides debounce delay and allows GATE to be ramped up at an adjustable rate. After start-up, the quiescent current drops to 4µA during normal operation with output active. The UVL, UVH, OV and GNDSW pins monitor overvoltage and undervoltage periodically by keeping total quiescent current low. Pulling SHDN low shuts down the LTC4231-2 and quiescent current drops to 0.3µA. The device automatically reapplies power after cool down period.
