www.DataSheet4U.com Freescale Semiconductor Advance Information Document Number: MC34653 Rev. 8.0, 2/2007 1.0 A Negative Voltage Hot Swap Controller The 34653 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-programmable limit, allowing the.
