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 loads 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 high and active low power good output
signals that can be used to directly enable a power module load.
Undervoltage and overvoltage detection circuitry monitors the input
voltage to check that it is within its operating range. A start-up delay
timer ensures that it is safe to turn on the Power MOSFET and charge
the load capacitor.
A two-level current limit approach to controlling the inrush current
and switching on the load limits the peak power dissipation in the
Power MOSFET. Both current limits are user programmable.
