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 have fault-

blanking. Die overtemperature faults and input voltage drops below the UVLO threshold

cause an immediate fault output.

3.2

Overcurrent/overtemperature protection

In overcurrent or short-circuit condition, the switch limits the current at 500 mA for

STMPS2242/STMPS2252 and 1000 mA for STMPS2262/STMPS2272. If the temperature

of the die goes above the limit value, the switch turns OFF.

3.3

Reverse current blocking

When the switch is OFF, or when the STMPS device is not powered (VCC=0 V), the switch

behaves as a Hi-Z at the output pin, ensuring that no reverse current will flow into the device

when VI<VO.

Note:

In the case where the switch is ON, and a voltage higher than VI is applied to the OUT pin, a

reverse current will occur.

3.4

UVLO

When the input voltage drops below the threshold value, the power switch turns OFF to

prevent improper operation due to low voltage.
