Working Principles

The MAX6365PKA31-T operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold voltage, the IC asserts the active-low reset output. This signal can be used to initiate a system reset or trigger other actions as required. The manual reset input allows for an external signal to override the internal monitoring and assert the reset output. The low quiescent current ensures minimal power consumption during operation.
