January 2013 Doc ID 13793 Rev 6 1/37 1 STMPS2141, STMPS2151, STMPS2161, STMPS2171 Enhanced single channel power switches Datasheet − production data Features ■ 90 mΩ high-side MOSFET switch ■ 500/1000 mA continuous current ■ Thermal and short-circuit protection with overcurrent logic output ■ Operating range from 2.7 to 5.5 V ■ CMOS and TTL compatible enable input ■ Undervoltage lockout (UVLO) ■ 12 µA maximum standby supply current ■ Ambient temperature range, -40 to 85 °C ■ 8 kV ESD protection ■ Reverse current protection ■ Fault blanking ■ UL recognized components (UL file number: E354278) 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.

STMPS2141, STMPS2151, STMPS2161, STMPS2171 Functional description Doc ID 13793 Rev 6 9/37 3 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 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 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 power switch applications, 4 types of fault conditions are common. These fault conditions and the response of the STMPS21x1 power switches are described in Table 3. Table 3. Fault conditions Fault Condition STMPS21x1 action Short-circuit Output shorted to GND via resistance path of < 1 Ω, causing a rapid current surge. Reduces output voltage to reduce the current. Asserts FAULT pin after a blanking period Overcurrent Output connected to a load that sinks current above threshold. Reduces output voltage to reduce the current. Asserts FAULT pin after a blanking period. Overheating Temperature of junction exceeds 135 °C due to any reason. Turn OFF output until temperature falls below 125 °C. Asserts FAULT pin immediately. Undervoltage Input voltage drops below the UVLO threshold. Turn OFF output until input voltage rises above the UVLO threshold plus hysteresis. Asserts FAULT pin immediately.
