Additional Details

The S-80825CLNB voltage detector provides a reliable and cost-effective solution for monitoring power supply voltages. It has a preset detection voltage level, which is 2.5V in the case of S-80825. The low current consumption is particularly important in battery-powered applications. The built-in hysteresis helps to prevent the output from oscillating when the input voltage is near the threshold. The SOT-23-5 package is a standard surface-mount package that is easy to handle during manufacturing. When using this voltage detector, it is essential to select the appropriate detection voltage for the application. The output signal can be used to reset a microcontroller or disable other circuits if the voltage falls below the threshold. This part is typically used with a pull-up resistor on the output. This combination of features makes it a good choice for basic system protection.
