Additional Details

The S-80833CNMA-B8S has a typical detection voltage of 3.3V. The low current consumption is crucial for battery operated applications. The open drain output allows flexible configuration with external pull-up resistors. The built-in hysteresis prevents chattering or oscillations around the threshold voltage, ensuring a clean and stable reset signal. The small SOT-23-3 package is optimal for saving space on printed circuit boards. This IC operates over a wide temperature range. The primary function of the voltage detector is to continuously monitor the input voltage and assert a reset signal when the voltage drops below the specified threshold. This reset signal can be used to reset a microcontroller or other digital circuit, preventing it from operating with an insufficient voltage level. The open-drain output requires an external pull-up resistor to provide the desired logic level. This allows the designer to select the appropriate voltage level for the reset signal.
