The LM5069MM-2/NOPB is a 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 N-Channel 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 LM5069-2 automatically restarts at a fixed duty cycle.
