Additional Details

The S-80834CNMA-B8T-G boasts a precise detection voltage of 3.4V. Its ultra-low current consumption makes it suitable for battery-powered applications. The built-in hysteresis prevents unwanted oscillations around the detection threshold. The SOT-23-3 package allows for easy integration, and the open-drain output provides design flexibility. The voltage detector continuously monitors the input voltage, asserting the output low when the input voltage drops below the detection threshold. This reset signal prevents the connected microcontroller from operating under potentially unstable or damaging low-voltage conditions. The open-drain output allows for external pull-up resistor selection, adapting to different voltage levels. The G suffix probably indicates that the product is lead-free.
