APPLICATION INFORMATION
The TPS2400 circuit in Figure 5 limits the inrush current without these draw backs. The TPS2400 charges the
transistor Q1 gate capacitance CG with a 5-A source when Q1 is commanded to turn on. Transistor Q1 is wired
as a source follower so the gate-voltage slew rate and the load-voltage slew rate are identical and equal to
V

The corresponding inrush current is:

An external capacitor and a series 1-k
resistor can be connected to the gate of Q1 and ground to reduce inrush
current further. In this case, the parameter CG in equations 1 and 2 is the sum of the internal and external FET
gate capacitance. The 1-k
resistor decouples the external gate capacitor so the TPS2400 can rapidly turn off
transistor Q1 in response to an overvoltage condition.
