The LM5067 negative 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 LM5067 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). In addition, the LM5067 provides circuit protection by monitoring for over-current and over-voltage conditions. The POWER GOOD output indicates when the output voltage is close to the input voltage. The input under-voltage and over-voltage lockout levels and hysteresis are programmable, as well as the fault detection time. The LM5067-1 latches off after a fault detection, while the LM5067-2 automatically attempts restarts at a fixed duty cycle. The LM5067 is available in a 10-pin VSSOP package and a 14-pin SOIC package.
