1 / 34 page  July 2009 Doc ID 13793 Rev 4 1/34 34 STMPS2141, STMPS2151 STMPS2161, STMPS2171 Enhanced single channel power switches Features ■ 90 m Ω 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 µA maximum standby supply current ■ Ambient temperature range, -40°C to 85°C ■ 8 kV ESD protection ■ Reverse current protection ■ Fault-blanking 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 Ω N-channel MOSFET high-side power switches for power-distribution. These switches are controlled by a logic enable input. Table 1. Device summary 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.
