LM5069 - Positive High-Voltage Hot Swap and In-Rush Current Controller

General 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.

Key Features

  • 1 Wide operating range: 9 V to 80 V.
  • 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 overcurrent events.
  • Internal high side charge pump and gate driver for external N-channel MOSFET.
  • Adjustable undervoltage lockout (UVLO) and hysteresis.
  • Adjustable overvoltage lockout (OVLO.
