Product Description
STMicroelectronics STMPS2161STR is a high-side power switch IC engineered for effective power distribution in electronic circuits. With a low RdsOn value of 90 mΩ, this IC provides efficient power switching capabilities, minimizing power losses and heat generation. The STMPS2161STR supports a continuous output current of up to 1 ampere, making it ideal for applications involving heavy capacitive loads and short-circuit protection.
This device operates within a supply voltage range of 2.7 V to 5.5 V, offering flexibility for integration into a wide variety of power management scenarios. It is delivered in an industry-standard SOT-23 surface mount package, featuring five pins for easy PCB mounting and space-saving design. Multiple built-in protective features, including thermal shutdown and short circuit protection, help maintain operational reliability under demanding conditions.
The STMPS2161STR is compatible with both CMOS and TTL level enable inputs, enabling seamless operation with multiple microcontroller and logic systems. This intelligent power switch incorporates under voltage lockout (UVLO) to safeguard circuits during voltage drops. Its maximum standby supply current of 12 μA promotes energy-efficient designs, especially in portable and low-power electronics.
Additional features include UL (E354278) approval, robust operational temperature range from -40°C to 85°C, and a compact dimensional profile with height 1.3 mm, length 3 mm, and width 1.75 mm. It does not fulfill automotive standards, focusing instead on industrial and commercial electronics requirements. Series designation is STMPS2161, reflecting its enhanced single-channel architecture within the STMPS21xx family.
Applications for the STMPS2161STR high-side power switch IC include industrial and commercial power management, laboratory instrumentation, portable devices, and manufacturing control systems. Its reliability and protective functions make it suitable for environments where power efficiency and safety are critical.
