Supervisory ICs

Supervisory ICs from ADI feature a range of the industry's most accurate microprocessor supervisors and reset generators. As processor core voltages decrease, the accuracy required to reliably monitor them increases. From the simple three pin Reset Generators in tiny SC-70 packages, to the more sophisticated Watchdog & Battery Backup Supervisor ICs and multi voltage supervisors and sequencers, there's a part to suit most applications.
