Additional Details

The XC61CN3802MR-G features a specific detection voltage (Vdet), which is typically indicated in the part number or datasheet. The '3802' likely corresponds to a detection voltage close to 3.8V or 3.80V, but the datasheet should be consulted for exact specifications. The reset output is typically an active-low signal, meaning it is low when the input voltage is below the detection threshold and high when the input voltage is above the threshold. Hysteresis is incorporated to prevent the output from oscillating due to noise or small voltage fluctuations around the detection threshold. The device requires minimal external components, typically just a pull-up resistor on the reset output. The package type is often SOT-23 or similar, designed for surface mount technology.
