  • 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.

    Key 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)
