Product Description
The STMicroelectronics STMPS2141STR is a high-quality high side MOSFET power switch integrated circuit designed for power management applications. The compact 5-pin SOT-23 package enables easy surface mounting, making it ideal for space-constrained electronics.
Operating from a low supply voltage of 2.7V up to 5.5V, this device supports continuous current of up to 500mA with a low Rds(on) of 160mΩ to minimize conduction losses. It incorporates intelligent protection features including thermal and short circuit protection with an overcurrent logic output, enhancing system reliability and safety during heavy capacitive loads and fault conditions.
The STMPS2141STR accepts enable inputs compatible with both CMOS and TTL logic families, facilitating flexible control methods. Its operating temperature range from -40°C to 125°C allows reliable operation in automotive and industrial environments, although it does not comply with automotive standards.
Its built-in Under Voltage Lockout (UVLO) prevents undesired activation at supply voltages below the minimum threshold, while a very low standby current of 12 microamps ensures energy efficiency during idle states.
This power switch IC is part of the STMPS21 series, widely used in electronic components, power connectors, and semiconductor power management systems. Its compact size (3mm length, 1.75mm width, and 1.3mm height) facilitates integration into modern electronic assemblies.
The device ensures optimized power distribution and protection for sensitive electronic circuits. Thermal shutdown and fault signaling features enhance overall device and system robustness. Designed for use in industrial, laboratory, electronic components manufacturing, and power supply equipment.
Low quiescent current aids battery-powered and low-power system applications. Packaging and pin configuration follow industry standards for seamless PCB design.
Choose the STMPS2141STR for reliable, efficient high side switching in your power management design projects. Explore additional Power Switch ICs and STMicroelectronics products available at EnvMart for comprehensive solutions.
