Supervisor IC with a 4.62V threshold and active-high assertion
The ADM1812-5ARTZ-RL7: The reset output is active high with a push-pull, totem-pole structure, so it drives a logic high when the supply is out of tolerance and does not require an external pull-up resistor. A minimum reset timeout of 100 ms holds the processor in reset long enough for the supply to stabilize after a brownout or power-up event.
Where the 4.62 V threshold fits in a 5 V system
With a threshold of 4.62 V, this part is designed for a nominal 5 V supply rail — it trips before the rail drops below the minimum operating voltage of most 5 V logic, giving the supervisor time to assert reset before data corruption occurs.
