Additional Details

The R3112Q301C-TR features a detection voltage of 3.0V. It is commonly used to reset a microcontroller when the supply voltage drops below this level, thus preventing unpredictable operations or data corruption. The low quiescent current consumption makes it suitable for battery-powered devices where minimizing power drain is critical. The built-in hysteresis prevents unwanted resets due to minor voltage variations or noise. The open-drain output allows for versatile connection to other circuits, typically through a pull-up resistor. The device is generally available in a small surface-mount package such as SOT-23, making it well-suited for high-density PCB layouts. The operating temperature range typically spans from -40°C to +85°C, enabling its use in a wide variety of environments. The tape and reel packaging simplifies automated assembly processes, improving manufacturing efficiency and reducing costs.
