Product Description
STMicroelectronics STMPS2141MTR is a high side MOSFET power switch designed for robust power management in electronic systems. This 8-pin SO package device offers low on-resistance (110mΩ) which reduces power loss and improves efficiency in power distribution applications. It supports supply voltages from 2.7 V up to 5.5 V and handles continuous operating currents up to 12 A, making it ideal for powering heavy capacitive loads and handling short-circuit conditions.
The switch includes integrated thermal protection circuitry that automatically disables the output in case of excessive temperature, preventing device damage. It also features short-circuit and overcurrent protection with a constant current mode to protect both the device and the load. The undervoltage lockout (UVLO) ensures the power switch only operates when the input voltage is within the specified range. The device consumes minimal quiescent current (12 μA) in standby mode, maximizing energy efficiency.
This surface mount package device is compact, measuring 5 mm in length, 4 mm in width, and 1.65 mm in height, facilitating integration into space-constrained designs. It is compliant with UL safety standard E354278 and functions reliably over a wide temperature range from -40°C to 125°C, suitable for industrial, automotive (non-automotive standard), and consumer electronics applications.
The STMPS2141MTR is commonly used in power distribution circuits requiring reliable high-side switching, such as battery protection, portable devices, and embedded systems. Its built-in fault blanking and reverse current protection add robustness to power management designs.
Low on-resistance switch (110mΩ) reduces power dissipation. Wide operating voltage from 2.7 to 5.5 V for versatile applications. Thermal shutdown and current limit protect the device and load. Compatible with CMOS and TTL logic enable inputs.
Low quiescent current of 12 μA increases battery life in portable devices. Compact SO-8 package eases PCB assembly and space saving. UL approved for assured quality and safety.
