Working Principles

The MAX6385XS16D1-T operates by continuously monitoring the supply voltage. When the voltage drops below the programmed threshold, the reset output is asserted, indicating that the system should be reset. The programmable delay feature allows for a specified time interval before asserting the reset signal, ensuring that the power supply stabilizes before restarting the system. The manual reset input can be used to override the monitoring function and manually assert the reset signal.
