Detailed Specs

The XC61GN2402HR boasts a high level of accuracy in its voltage detection, typically within ±1%. It's designed for ultra-low current consumption, making it suitable for battery-operated devices where energy conservation is paramount. The SOT-25 package allows for a compact footprint on the circuit board. The integrated hysteresis prevents oscillations and ensures a clean, stable reset signal. The open drain output offers versatile connection options to different logic levels and microcontrollers. The device typically operates over a temperature range of -40°C to +85°C. The device functions by continuously monitoring the input voltage. When the voltage drops below the 2.4V threshold, the open drain output pulls low, indicating a reset condition. Once the input voltage rises above the threshold plus the hysteresis voltage, the output releases (pulled high by an external resistor).

The XC61GN2402HR is a vital component for ensuring the robust and reliable operation of electronic systems by providing essential voltage monitoring and reset functionality.
