The LM5069 positive 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 LM5069 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). The POWER GOOD
output indicates when the output voltage is within 1.25V of the
input voltage. The input under-voltage and over-voltage lockout
levels and hysteresis are programmable, as well as the
initial insertion delay time and fault detection time. The
LM5069-1 latches off after a fault detection, while the
LM5069-2 automatically restarts at a fixed duty cycle. The
LM5069 is available in a 10 pin MSOP package.
