When the supply voltage falls below a preset threshold, the IC asserts a reset signal to keep the system in a safe, known state. The push-pull output (as opposed to open-drain) provides fast, strong signal transitions, making it well-suited for noise-sensitive or high-speed designs. The SOT-143 package keeps board footprint minimal while maintaining solid thermal performance.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrocontroller \/ microprocessor supervisory circuits\u003c\/li\u003e\n  \u003cli\u003eEmbedded system reset control\u003c\/li\u003e\n  \u003cli\u003ePower management and brown-out detection\u003c\/li\u003e\n  \u003cli\u003eIndustrial control boards and consumer electronics\u003c\/li\u003e\n  \u003cli\u003ePrototyping, R\u0026amp;D labs, and electronics repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e10 × CAT811STBI-GT3 SOT-143 Integrated Circuit (brand new)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eRelated Products You May Find Useful\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/electromagnetic-induction-tester-coil-motherboard-fault-detector\"\u003eElectromagnetic Induction Tester – Coil \u0026amp; Circuit Fault Detector\u003c\/a\u003e — great companion tool for diagnosing circuit board issues\u003c\/li\u003e\n  \u003cli\u003e\n\u003ca href=\"\/products\/air-compressor-pressure-gauge-0-10-0-12-0-25-bar-hydraulic-diy\"\u003eAir Compressor Pressure Gauge 0-10\/0-12\/0-25 Bar | DIY Tool\u003c\/a\u003e — handy for your electronics workbench setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/www.energystar.gov\/products\" target=\"_blank\" rel=\"noopener\"\u003eENERGY STAR product efficiency guidance\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: What is the CAT811STBI-GT3 integrated circuit used for?\u003c\/h4\u003e\n\u003cp\u003eA: The CAT811STBI-GT3 is a push-pull output voltage monitor IC used primarily as a microprocessor supervisory circuit. It monitors supply voltage and generates a reset signal when voltage drops below a defined threshold, ensuring your microprocessor or digital system restarts in a controlled and reliable manner.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What package does the CAT811STBI-GT3 come in?\u003c\/h4\u003e\n\u003cp\u003eA: The CAT811STBI-GT3 comes in the SOT-143 surface-mount package.
