Overview

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.

  • 2 Wide operating range: -9V to -80V
  • 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
