Working Principles

The MAX6383XR23D1-T operates by continuously monitoring the voltage level at the VCC pin. When the voltage falls below the selected threshold voltage (determined by the TH pin), the IC generates an active-low reset signal at the RESET pin. This signal can be used to reset microcontrollers or other digital systems, ensuring a reliable power-on reset.
