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 system to safely stabilize.
A disable function allows the user to disable the 34653 manually or through a microprocessor and safely disconnect the load from the main power line.
The 34653 has active ...
