The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 /ADM8322 are supervisory circuits that monitor power supplyvoltage levels and code execution integrity in microprocessor-basedsystems. As well as providing power-on reset signals, an on-chipwatchdog timer can reset the microprocessor if it fails to strobewithin a preset timeout period. A reset signal can also be assertedby an external push-button switch through a manual reset input.The six devices feature different combinations of watchdoginput, manual reset input, and output stage configuration.Each device is available in a choice of 27 reset threshold optionsranging from 2.5 V to 5 V in 100 mV increments. There are alsofour reset timeout options of 1 ms, 20 ms, 140 ms, and 1120 ms(minimum) and four watchdog timeout options of 6.3 ms, 102 ms,1.6 sec, and 25.6 sec (typical). Not all device options are availableas standard models. See the Ordering Guide for details.The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 /ADM8322 are available in 5-lead SOT-23 packages and typicallyconsume only 10 µA, making them suitable for use in lowpower, portable applications.Applications Automotive infotainment Microprocessor systems Computers Controllers Intelligent instruments Portable equipment
