The LM25061PMME-2/NOPB is a positive Hot Swap Controller provides intelligent control of the power supply voltage to the load during insertion and removal of circuit cards from a live system backplane or other "hot" power sources. The LM25061 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 exceeds a programmable threshold. The input under-voltage level and hysteresis are programmable, as well as the initial insertion delay time and fault detection time. The LM25061-2 automatically restarts at a fixed duty cycle.
