Additional Details

The S-80931ALMP-DAVT2G employs an open-drain output, allowing for flexible connection to various logic families and voltage levels. The inclusion of hysteresis prevents the generation of false reset signals caused by minor voltage fluctuations near the threshold. This voltage detector is commonly used to monitor the power supply voltage of microcontrollers, microprocessors, and other critical components in electronic systems. When the voltage dips below the defined detection threshold, the device asserts a reset signal, ensuring that the system is properly initialized or shut down to prevent data corruption and unpredictable behavior. The ultra-low current consumption of the S-80931ALMP-DAVT2G makes it highly suitable for battery-powered applications where minimizing power drain is essential. The small SOT-23-5 package allows for easy integration into densely populated circuit boards. The high-accuracy detection voltage ensures precise and reliable voltage monitoring.
