STMPS2151STR

The STMPS2141, STMPS2151, STMPS2161,
STMPS2171 power distribution switches are
intended for applications where heavy capacitive
loads and short-circuits are likely to be
encountered. These devices incorporate 90 mW
N-channel MOSFET high-side power switches for
power distribution. These switches are controlled
by a logic enable input.
When the output load exceeds the current limit
threshold or a short is present, the device limits
the output current to a safe level by switching into
a constant current mode. 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 the switch off to prevent damage. Recovery
from a thermal shutdown is automatic once the
device has cooled sufficiently. Internal circuitry
ensures the switch remains off until a valid input
voltage is present.
