Figure 29. Hybrid Self / Bus-Powered Hub Implementation
GENERIC HOT-PLUG APPLICATIONS
In many applications it may be necessary to remove modules or pc boards while the main unit is still operating.
These are considered hot-plug applications. Such implementations require the control of current surges seen by
the main power supply and the card being inserted. The most effective way to control these surges is to limit and
slowly ramp the current and voltage being applied to the card, similar to the way in which a power supply
normally turns on. Due to the controlled rise times and fall times of the TPS206x, these devices can be used to
provide a softer start-up to devices being hot-plugged into a powered system. The UVLO feature of the TPS206x
also ensures that the switch is off after the card has been removed, and that the switch is off during the next
insertion. The UVLO feature insures a soft start with a controlled rise time for every insertion of the card or
module.
