| STMPS2141, STMPS2151 STMPS2161, STMPS2171 Enhanced single channel power switches Features 90 m high-side MOSFET switch 500/1000 mA continuous current Thermal and short-circuit protection with overcurrent logic output Operating range from 2.7 V to 5.5 V CMOS- and TTL-compatible enable inputs Undervoltage lockout (UVLO) 12 A maximum standby supply current Ambient temperature range, -40C to 85C 8 kV ESD protection Reverse current protection Fault-blanking MSOP8 SOT23-5L SO-8 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 m 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. Table 1.

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 power switch applications, 4 types of FAULT conditions are common. These fault conditions and the response of the STMPS21x1 power switches are described in the following Table 3. Table 3. Fault Short circuit FAULT conditions Condition Output shorted to GND via resistance path of < 1 causing a rapid current , surge. Output connected to a load that sinks current above threshold. STMPS21x1 action Reduces output voltage to reduce the current. Asserts FAULT pin after a blanking period Reduces output voltage to reduce the current. Asserts FAULT pin after a blanking period. Over-current Overheating Turn OFF output until temperature falls Temperature of junction exceeds 135C below 125C. Asserts FAULT pin due to any reason. immediately. Input voltage drops below the UVLO treshold. Turn OFF output until input voltage rises above the UVLO treshold plus hysteresis. Asserts FAULT pin immediately. Undervoltage Doc ID 13793 Rev 4 9/34 Functional description STMPS2141, STMPS2151, STMPS2161, STMPS2171 3.4 Reversed current blocking When the switch is OFF (disabled through the EN pin), or when the STMPS device is unpowered (VCC = 0 V) the switch behaves as an 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 VIN is applied to the OUT pin, a reverse current occurs. This operating condition is not allowed. 3.5 UVLO When the input voltage drops below critical values, the power switch turns off to prevent improper operation due to low voltage. 10/34 Doc ID 13793 Rev 4 STMPS2141, STMPS2151, STMPS2161, STMPS2171 Ambient temperature 4 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. Table 4.
