is a dual power distribution
switch intended for
applications where
heavy capacitive loads
and short-circuits
are likely to be encountered.
The high-side switch
is a 95m N-channel
MOSFET. The switch
is controlled by a
logic enable input
compatible with 3V
and 5V logic and is
available in active-high
or active-low enable.
The internal charge
pump, designed to
control the power
switch rise and fall
time to minimize current
surges during switching,
also provides the
gate drive. Requiring
no external components
the charge pump allows
operation from supplies
as low as 4.0V. When
an overload or a short
circuit is encountered
the AMS2026 limits
the output current
to a safe level by
switching into a constant-current
mode and the over
current logic output
error flag is set
to a low. Continuous
heavy overloads and
short circuits will
increase the power
dissipation in the
switch; this will
cause the junction
temperature to rise.
The thermal protection
circuit shuts the
power switch off to
prevent damage. Once
the device has cooled
sufficiently, it will
turn on automatic.
An under voltage
lock-out is provided
to insure that the
power switch is in
the Off state at start-up.
The
AMS2026 is used in
USB power management,
hot plug-in power
supplies and battery
charger circuits.
