DESCRIPTION
The
ST2054
power
distribution
switches
is
intended for application where heavy capacitive
loads
and
short
circuits
are
likely
to
be
encountered. These devices incorporate 80m
N-channel MOSFET high-side power switches for
power-distribution systems that require multiple
powers switches in a single package. Each switch
is controlled by an independent logic enable input.
Gate drive is provided by an internal charge pump
designed to control the power-switch rise times
and fall times to minimize current surges during
switching. The charge pump requires no external
components and allows operation from supplies
as low as 2.7 V.
When the output load exceeds the current-limit
threshold or a short is present, these devices limit
the output current to a safe level by switching into
a constant-current mode, pulling the overcurrent
(OCx) logic output low. A 10ms deglitching circuit
provides fault-blanking feature, preventing the
OC_N pin to be asserted during hot-insertion or
short spikes of overcurrent conditions.
When continuous heavy overloads and short
circuits increase the power dissipation in the
switch, causing the junction temperature to rise, a
thermal protection circuit shuts off the switch to
prevent
damage.
Recovery
from
a
thermal
shutdown is automatic once the device has cooled
sufficiently. Internal circuitry ensures the switch
remains off until valid input voltage is present.
These power-distribution switches are designed to
current limit at 0.9 A.
