... Hot Swap Controller General Description The Supertex HV301 Hot Swap Controller provides inrush current limiting and other power supply support functions for hot swap equipment. Current limiting is provided by control of an external MOSFET which is placed in the return line of the power supply connection. Placement in the return allows use of an N-channel MOSFET without the need for high side driving ...
