Features
Description
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 mΩ
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.
