Notes
1. Refer to the section titled Power MOSFET Energy Capability on page 22 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=100pF, RZAP=1500 ).
4. ESD2 testing is performed in accordance with the Machine Model (CZAP=200 pF, RZAP=0 ).
5. The limiting factor is junction temperature, taking into account power dissipation, thermal resistance, and heatsinking.
6. Terminal 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.
7. Refer to the section titled Thermal Shutdown on page 15 for more thermal resistance values under various conditions.
8. The VOUT and VIN terminals 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.

Description

The 34652 is a highly integrated -48 V hot swap controller with an internal Power MOSFET. 34652provides 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 34652 manually or through a microprocessor and safely disconnect the load from the main power line.

The 34652 has active high and active low power good output signals that can be used to directly enable a power module load. Programmable under- and overvoltage detection circuitry monitors the input voltage to check that it is within its operating range. A programmable 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 of 34652 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.
