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.
Table 1.
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.

Functional description
3.1
Fault blanking
The STMPS devices feature a 10 ms fault blanking. Fault blanking allows current-limit faults,
including momentary short-circuit faults that occur when hot-swapping a capacitive load,
and also ensures that no fault is issued during power-up. When a load transient causes the
device to enter current limit, an internal counter starts. If the load fault persists beyond the
10 ms fault-blanking timeout, the FAULT output asserts “low”. Load-transient faults less than
10 ms (typ.) do not cause a FAULT output assertion. Only current-limit faults are blanked.
Die over-temperature faults and input voltage drops below the UVLO threshold cause an
immediate fault output.
3.2
Overcurrent/over-temperature protection
In overcurrent or short-circuit condition, the switch limits the current at a value of about
120% of the rated current. If the temperature of the die goes above the limit value, the switch
turns off.
3.3
FAULT conditions
In applications of power switch, 3 types of FAULT conditions are common. These fault
conditions and the response of STMPS21x1 power switches are described in the following
table.

Functional description
Reversed current blocking
When the switch is OFF, or when the STMPS device is un-powered (VCC = 0V), the switch
behaves as an Hi-Z at the output pin, ensuring that no reverse current will flow into the
device.
Note:
In the case where the switch is ON, and a voltage higher than VIN is applied to the OUT pin,
a reverse current occurs. This operating condition is not allowed.
3.5
UVLO
When input voltage drops below critical value, the power switch turns off to prevent improper
operation due to low voltage.

STMPS2141, STMPS2151, STMPS2161, STMPS2171
Ambient temperature
In Enable operating mode, an amount of power is dissipated as heat in the power switch due
to the on-resistance. The power dissipation is: P = I2R

Maximum rating
Stressing the device above the rating listed in the “Absolute Maximum Ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
