Application Note
Under-voltage Lockout (UVLO)
Under-voltage lockout function (UVLO) keeps the internal
power switch from being turned on until the power supply
has reached at least 1.9V, even if the switch is enabled.
Whenever the input voltage falls below approximately
1.9V, the power switch is quickly turned off. This facilitates
the design of hot-insertion systems where it is not possible
to turn off the power switch before input power is removed.
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
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 AP2145/AP2155, 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
AP2145/AP2155 also ensures that the switch is off after
the card has been removed, and that the switch is off
during the next insertion.
By placing the AP2145/AP2155 between the V
and the rest of the circuitry, the input power reaches
these devices first after insertion. The typical rise time of
the switch is approximately 1ms, providing a slow voltage
ramp at the output of the device. This implementation
controls
hot-plugging mechanism for any device.
