Additional Details

The S-80945CNNB-G9FT2U is a highly integrated voltage detector that ensures reliable system operation by monitoring the supply voltage. It features a precise detection voltage of 4.5V. When the input voltage drops below this threshold, the detector asserts a reset signal. The built-in hysteresis prevents the output from oscillating when the input voltage is near the threshold, ensuring a clean and stable reset. This feature is particularly important in noisy environments. Its low current consumption makes it suitable for battery-powered applications where energy efficiency is critical. The SOT-23 package allows for easy integration into compact electronic designs. This voltage detector is widely used in a variety of applications, including microcontroller-based systems, power supplies, and battery management systems. By providing a reliable reset signal, it helps to prevent data corruption, system crashes, and other undesirable effects caused by undervoltage conditions. The precise detection threshold and hysteresis characteristics, combined with low current consumption and small package size, make the S-80945CNNB-G9FT2U an excellent choice for voltage monitoring applications.
