8.0, 2/2007 2.0 A Negative Voltage Hot Swap Controller with Enhanced Programmability The 34652 is a highly integrated - 48 V hot swap controller with an internal Power MOSFET.

It provides the means to safely install and remove boards from live - 48 V backplanes without having to power down the entire system.

It regulates the inrush current, from the supply to the load’s filter capacitor, to a user-pr
