GENERAL DESCRIPTION

The ADM8616/ADM8617 are supervisory circuits that monitor

power supply voltage levels and code execution integrity in

microprocessor-based systems. A power-on reset signal is

generated 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.

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.

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.
