HV300 Overview
The Supertex HV300, Hotswap Controller, Negative Supply controls the power supply connection during insertion of cards or modules into live backplanes. It may be used in traditional ‘negative 48V’ powered systems or for higher voltage busses up to negative 90V. Operation during the initial power up prevents turn-on glitches, and after plete charging of load capacitors (typically found in filters at the input of DC-DC...
