A power-on reset signal generates when the supply voltage rises to a preset threshold level.
The ADM8616/ ADM8617 have an on-chip watchdog timer that can reset the microprocessor if it fails to strobe within a preset timeout period.
Each part is available in the following nine reset threshold options: 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.
Not all device options are released for sale as standard models.
See the Ordering Guide for details.

04795-001 The parts differ in terms of reset output configuration.
The ADM8616 is active-low with a push-pull output, while the ADM8617 is active-low with an open-drain output.
The ADM8616/ADM8617 are available in 4-lead SC70 packages and typically consume only 5 μA, making them suitable for use in low power, portable applications.
