hysteresis
• Adjustable overvoltage 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
• Available in latched fault and automatic restart
versions
• 10-Pin VSSOP package
2 Applications
• Server backplane systems
• Base station power distribution systems
• Solid state circuit breaker
• 24-V and 48-V Industrial systems
3 Description
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.
