The ADM8616/ADM8617 are supervisory circuits that monitorpower supply voltage levels and code execution integrity in micro-processor-based systems. A power-on reset signal generates whenthe supply voltage rises to a preset threshold level. The ADM8616/ADM8617 have an on-chip watchdog timer that can reset themicroprocessor if it fails to strobe within a preset timeoutperiod.
Each part is available in the following nine reset thresholdoptions: 1.58 V, 1.67 V, 2.19 V, 2.32 V, 2.63 V, 2.93 V, 3.08 V, 4.38 V, and 4.63 V. There are four reset timeout options: 1 ms,20 ms, 140 ms, and 1120 ms. There are also three possible watchdog timeouts available: 6.3 ms, 102 ms, and 1.6 sec. Notall device options are released for sale as standard models. Seethe Ordering Guide for details.
The parts differ in terms of reset output configuration. TheADM8616 is active-low with a push-pull output, while theADM8617 is active-low with an open-drain output.
The ADM8616/ADM8617 are available in 4-lead SC70 packagesand typically consume only 5 μA, making them suitable for usein low power, portable applications.
