Supervisors

ADI has a wide range of the industries 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 Supervisors and multi voltage supervisor and sequencers, there's a part to suit most applications.
