LM5069 - Positive High Voltage Hot Swap / Inrush 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

  • n Wide operating range: +9V to +80V n In-rush current limit for safe board insertion into live power sources n Programmable maximum power dissipation in the external pass device Package n MSOP-10 Typical.

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 1.25V of the input voltage.
