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
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
