The LM5067 negaTIve hot swap controller provides intelligentcontrol of the power supply connecTIons during inserTIon andremoval of circuit cards from a live system backplane or other“hot” power sources. The LM5067 provides in-rush currentcontrol to limit system voltage droop and transients. The currentlimit and power dissipaTIon in the external series pass NChannelMOSFET are programmable, ensuring operationwithin the Safe Operating Area (SOA). In addition, theLM5067 provides circuit protection by monitoring for overcurrentand over-voltage conditions. The POWER GOODoutput indicates when the output voltage is close to the inputvoltage. The input under-voltage and over-voltage lockoutlevels and hysteresis are programmable, as well as the faultdetection time. The LM5067-1 latches off after a fault detection,while the LM5067-2 automatically attempts restarts at afixed duty cycle. The LM5067 is available in a 10 pin MSOPpackage and a 14 pin SOIC package.
