CIRCUIT DESCRIPTION The ADM823/ADM824/ADM825 provide microprocessor supply voltage supervision by controlling the microprocessor’s reset input. Code-execution errors are avoided during power- up, power-down, and brownout conditions by asserting a reset signal when the supply voltage is below a preset threshold. ...

ADM823/ADM824/ADM825 APPLICATION INFORMATION WATCHDOG INPUT CURRENT In order to minimize watchdog input current (and minimize overall power consumption), leave WDI low for the majority of the watchdog timeout period. When driven high, WDI can draw as much as 160 μA. ...
