Working Principles

The DS1236A-5N operates by continuously monitoring the supply voltage through the SENSE pin. It compares the sensed voltage with the user-defined threshold voltage. If the supply voltage drops below the threshold, the IC generates an active-low reset signal on the RESET pin. This signal is used to reset the system and ensure proper initialization.

The threshold voltage can be adjusted by connecting external resistors to the SENSE pin. Similarly, the reset timeout period can be programmed by connecting an external capacitor to the MR pin. These features allow customization based on specific application requirements.
