ADM8321 Supervisory Circuits

The ADM8316/ADM8318/ADM8319/ADM8320/ADM8321/ ADM8322 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessorbased systems. As well as providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strob.
