The LM5067 negative hot swap controller provides intelligent
control of the power supply connections during insertion and
removal of circuit cards from a live system backplane or other
“hot” power sources. The LM5067 provides in-rush current
control to limit system voltage droop and transients. The current
limit and power dissipation in the external series pass NChannel
MOSFET are programmable, ensuring operation
within the Safe Operating Area (SOA). In addition, the
LM5067 provides circuit protection by monitoring for overcurrent
and over-voltage conditions. The POWER GOOD
output indicates when the output voltage is close to the input
voltage. The input under-voltage and over-voltage lockout
levels and hysteresis are programmable, as well as the fault
detection time. The LM5067-1 latches off after a fault detection,
while the LM5067-2 automatically attempts restarts at a
fixed duty cycle. The LM5067 is available in a 10 pin MSOP
package and a 14 pin SOIC package.
