The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 / ADM8322 are supervisory circuits that 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. A reset signal can also be asserted by an external push-button switch through a manual reset input. The six devices feature different combinations of watchdog input, manual reset input, and output stage configuration.
Each device is available in a choice of 27 reset threshold options ranging from 2.5 V to 5 V in 100 mV increments. There are also four 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 available as standard models. See the Ordering Guide for details.
The ADM8316 / ADM8318 / ADM8319 / ADM8320 / ADM8321 / ADM8322 are available in 5-lead SOT-23 packages and typically consume only 10 µA, making them suitable for use in low power, portable applications.
