Detailed Specs

The XC61GN2902HR provides precise voltage detection with a typical accuracy of ±1%. Its low quiescent current consumption makes it well-suited for battery-powered applications where minimizing power drain is crucial. The compact SOT-25 package allows for efficient use of board space. The built-in hysteresis prevents unwanted oscillations and ensures a clean and stable reset signal. The open-drain output offers flexibility in interfacing with various microcontrollers and other digital circuits. The typical operating temperature range is from -40°C to +85°C. The device functions by continuously monitoring the input voltage. When the voltage drops below the 2.9V threshold, the open-drain output pulls low, signaling a reset condition. Once the voltage rises above the threshold plus the hysteresis voltage, the output is released (pulled high by an external resistor).

The XC61GN2902HR is a vital component in maintaining the integrity and reliability of electronic systems by providing a dependable voltage monitoring and reset function.
