Detailed Specs

The XC61GN3802HRN provides highly accurate voltage detection, typically within ±1% of the nominal 3.8V. Its low quiescent current consumption minimizes power drain, making it suitable for battery-powered applications. The compact SOT-25 package allows for dense board layouts. The integrated hysteresis prevents oscillations and ensures a clean reset signal. The open drain output offers flexibility in interfacing with various microcontrollers and other digital circuits. The typical operating temperature range spans from -40°C to +85°C. The device continuously monitors the input voltage. When the voltage drops below the 3.8V 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).

The XC61GN3802HRN is a crucial component for ensuring the reliable operation of electronic systems by providing essential voltage monitoring and a dependable reset mechanism, protecting against voltage drops and potential system malfunctions.
