• SOT-23-5 package may require additional space on the PCB compared to smaller packages

Working Principles

The ADM1816-5ARTZ-REEL monitors the power supply voltage using an internal voltage reference and comparator. When the voltage falls below the specified threshold, the reset output is activated, generating a low signal. This signal can be used to reset the microcontroller or other system components.

The reset timeout period determines how long the reset signal remains active after the voltage has returned above the threshold. The manual reset input allows the user to manually assert the reset signal, overriding the automatic monitoring function.
