Additional Details

The XC61GC3002HRN typically operates over a wide temperature range, usually from -40°C to +85°C, making it suitable for various operating environments. It is often available in small surface-mount packages, such as SOT-25, which facilitates easy integration into densely populated PCBs. The output signal is typically an open-drain configuration, requiring an external pull-up resistor for proper operation. The hysteresis feature helps to prevent oscillations around the threshold voltage, thereby ensuring a stable and reliable reset signal. The supply voltage range generally extends above the detection voltage to ensure the device functions correctly and reliably.
