Swap Controller
34653
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 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.

Notes
1. Refer to the section titled Power MOSFET Energy Capability on page 21 for a detailed explanation on this parameter.
2. Continuous output current capability so long as TJ is 160°C.
3. ESD1 testing is performed in accordance with the Human Body Model (CZAP=100 pF, RZAP=1500 ), ESD2 testing is performed in
accordance with the Machine Model (CZAP=200 pF, RZAP=0 ).
4. The limiting factor is junction temperature, taking into account power dissipation, thermal resistance, and heatsinking.
5. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may
cause malfunction or permanent damage to the device.
6. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow
Temperature and Moisture Sensitivity Levels (MSL),
Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts. (i.e.
MC33xxxD enter 33xxx), and review parametrics.
7. Refer to the section titled Thermal Shutdown on page 15 for more thermal resistance values under various conditions.
8. The VOUT and VIN pins comprise the main heat conduction paths.
9. Per SEMI G38-87 and JEDEC JESD51-2 with the single-layer board (JESD51-3) horizontal.
10. Per JEDEC JESD51-6 with the board (JESD51-7) horizontal. There are no thermal vias connecting the package to the two planes in the
board.
