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 N-Channel MOSFET are programmable, ensuring operation within the Safe Operating Area (SOA). The POWER GOOD output indicates when the output voltage is within 1.25 V of the input voltage. The input undervoltage and overvoltage 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. LM5069 is available in a 10-pin VSSOP package.
