ADV809 Datasheet PDF

ADV ADV809

The ADV809 and ADV810 are cost–effective system supervisorcircuits designed to monitor VCC in digital systems and provide a resetsignal to the host processor when necessary. The output of the ADV809 isguaranteed valid down to VCC = 1V. TheADV810 has an active–high RESET output while the ADV809 hasan active–low RESET output.
