... Computers Controllers Intelligent instruments Portable equipment GENERAL DESCRIPTION The ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/ADM6322 are supervisory circuits which monitor power supply voltage levels and code execution integrity in microprocessor-based systems. As well as providing power on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period ...
