Detailed Specs

The XC61GN2202HR offers high accuracy in voltage detection, typically within ±1%. Its low quiescent current consumption minimizes power drain, making it suitable for battery-operated devices. The small SOT-25 package allows for dense board layouts. The integrated hysteresis feature prevents oscillations and ensures a clean reset signal. The open drain output provides flexibility in connecting to different logic levels and microcontrollers. The typical operating temperature range is -40°C to +85°C. The device operates by constantly monitoring the input voltage. When the voltage drops below the 2.2V threshold, the open drain output is pulled 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).

In essence, the XC61GN2202HR is a crucial component for ensuring the reliable operation of electronic systems by safeguarding against voltage fluctuations and providing a stable reset mechanism.
