Working Principles

The MAX6313UK49D1-T operates by continuously monitoring the supply voltage connected to the VCC pin. It compares the voltage level with the set threshold voltage, which is determined by the TH pin. When the supply voltage falls below the threshold, the IC generates an active-low reset signal on the RESET pin. This signal can be used to reset microcontrollers, digital logic circuits, or other system components.

The reset timeout period can be adjusted using external timing components connected to the MR pin. This feature allows customization of the time delay between the voltage dropping below the threshold and the generation of the reset signal. The adjustable timeout period ensures compatibility with different system requirements.
