Additional Details:

The S-8423BAFS-T2 monitors the input voltage continuously. When the voltage falls below the predetermined threshold, the device activates its open-drain output, signaling a reset or fault condition. The hysteresis feature prevents chattering or oscillation near the threshold voltage, ensuring a stable and reliable output signal. The low current consumption makes it an excellent choice for battery-powered applications where power efficiency is critical. The device is typically available in a small SOT package for easy integration into compact electronic designs. The operating temperature range is generally between -40°C and +85°C. The specific detection voltage threshold is set during the manufacturing process to meet the requirements of different applications.
