The LM25069 posiTIve hot swap controller provides intelligentcontrol of the power supply voltage to the load during inserTIonand removal of circuit cards from a live system backplane orother "hot" power sources. The LM25069 provides in-rushcurrent control to limit system voltage droop and transients.The current limit and power dissipaTIon in the external seriespass N-Channel MOSFET are programmable, ensuring operaTIonwithin the Safe Operating Area (SOA). The POWERGOOD output indicates when the output voltage is within 1.3Vof the input voltage. The input under-voltage and over-voltagelockout levels and hysteresis are programmable, as well asthe initial insertion delay time and fault detection time. TheLM25069-1 latches off after a fault detection, while theLM25069-2 automatically restarts at a fixed duty cycle. TheLM25069 is available in a 10 pin MSOP package.
