STMPS2151MTR Datasheet

Power Switch ICs - Power Distribution


The STMPS2151MTR power distribution switches are intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. These devices incorporate 90 mΩN-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. STMPS2151MTR 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)
