Working Principles

The MAX6385XS19D1-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the threshold voltage (1.9V in this case), 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 components in the system.

The IC also includes a manual reset input (MR pin) that allows for a forced reset regardless of the voltage level. This feature is useful during system testing or when a controlled reset is required.
