The LM5067MM-2/NOPB is a 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, it 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 LM5067-2 automatically attempts restarts at a fixed duty cycle.

• In-rush current limit for safe board insertion into live power sources
• Programmable maximum power dissipation in the external pass device
• Adjustable current limit
• Circuit breaker function for severe over-current events
• Adjustable under-voltage lockout (UVLO) and hysteresis
• Adjustable over-voltage lockout (OVLO) and hysteresis
• Initial insertion timer allows ringing and transients to subside after system connection
• Programmable fault timer avoids nuisance trips
• Active high open drain POWER GOOD output
• Green product and no Sb/Br
