Housed in a compact SOT-23-5 package, it integrates a 70mΩ N-channel MOSFET with over-current, thermal, and reverse-current protection. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for 3.3V and 5V power rails. Its enable pin is active-high, and the fault flag output indicates over-current or thermal shutdown conditions.\u003c\/p\u003e\u003ch2\u003eDetailed Technical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e2.7V – 5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContinuous Output Current\u003c\/td\u003e\n\u003ctd\u003e0.5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-Resistance (typical)\u003c\/td\u003e\n\u003ctd\u003e70mΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Limit Threshold\u003c\/td\u003e\n\u003ctd\u003e0.75A (min), 1.5A (max)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuiescent Current (enabled)\u003c\/td\u003e\n\u003ctd\u003e25μA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShutdown Current\u003c\/td\u003e\n\u003ctd\u003e1μA (max)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnable Logic\u003c\/td\u003e\n\u003ctd\u003eActive High\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFault Flag Output\u003c\/td\u003e\n\u003ctd\u003eOpen-drain, active low\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +85°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eSOT-23-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIntegrated 70mΩ N-channel MOSFET power switch\u003c\/li\u003e\n\u003cli\u003eCurrent limiting to protect upstream power supplies\u003c\/li\u003e\n\u003cli\u003eThermal shutdown protection\u003c\/li\u003e\n\u003cli\u003eReverse-current blocking when disabled\u003c\/li\u003e\n\u003cli\u003eFault flag (open-drain) for over-current and thermal events\u003c\/li\u003e\n\u003cli\u003eUnder-voltage lockout (UVLO)\u003c\/li\u003e\n\u003cli\u003eLow quiescent current: 25μA typical\u003c\/li\u003e\n\u003cli\u003eCompact SOT-23-5 package for space-constrained designs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cp\u003eThe STMPS2141STR is ideal for power distribution and protection in a variety of systems, including:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e5G base stations: powering control logic and RF front-end modules\u003c\/li\u003e\n\u003cli\u003eAutomotive dashboard infotainment systems: protecting USB ports and sensors\u003c\/li\u003e\n\u003cli\u003eIndustrial PLCs: distributing power to I\/O modules\u003c\/li\u003e\n\u003cli\u003ePortable devices: battery-powered equipment with USB OTG\u003c\/li\u003e\n\u003cli\u003eSet-top boxes and smart home hubs: powering peripheral interfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"border-bottom:2px solid #eee; padding-bottom:10px; margin-top:40px;\"\u003e\n  Global Supply Chain \u0026amp; Wholesale Solutions\n\u003c\/h2\u003e\n\u003cp\u003eAt Jasin Chip, we provide professional supply chain and wholesale solutions for\n\u003cstrong\u003eSTMPS2141STR\u003c\/strong\u003e.
