9.3 Feature Description

9.3.1 Hot Plug-In and In-Rush Current Control

The devices are designed to control the in-rush current upon insertion of a card into a live backplane or

other hot power source. This design limits the voltage sag on the backplane’s supply voltage and prevents

unintended resets of the system power. The controlled start-up also helps to eliminate conductive and radiative

interferences. An external capacitor connected from the dVdT pin to GND defines the slew rate of the output

voltage at power-on. The fastest output slew rate of 24 V/500 µs can be achieved by leaving dVdT pin floating.

The inrush current can be calculated using Equation 1.
