ADM6317 - Supervisory Circuits

The ADM6316/ADM6318/ADM6319/ADM6320/ADM6321/ ADM6322 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.
