GENERAL DESCRIPTION

The ADM8611-EVALZ/ADM8612-EVALZ/ADM8613-EVALZ/
ADM8614-EVALZ/ADM8615-EVALZ boards demonstrate the
ADM8611/ADM8612/ADM8613/ADM8614/ADM8615
features summarized in Table 1. These ultra low power voltage
supervisors monitor the input voltage level and compare it against
an internal reference.
This user guide describes how to set up and use the boards to
demonstrate the product functions. Full details about the
ADM8611/ADM8612/ADM8613/ADM8614/ADM8615
available in the product data sheet, which must be consulted in
conjunction with this user guide when using the ADM8611-EVALZ/
ADM8612-EVALZ/ADM8613-EVALZ/ADM8614-EVALZ/
ADM8615-EVALZ.

The internal timer is cleared every time a logic of the status of the monitored input voltage by pressing the built transition of as short as 85 ns is detected on the ADM8613- in tact switch, JP1, which shorts the ADM8611-EVALZ/ EVALZ/ADM8614-EVALZ/ADM8615-EVALZ WDI pin. The ADM8612-EVALZ/ADM8613-EVALZ/ADM8615-EVALZ MR# watchdog timer can be disabled by driving the ADM8613-EVALZ/ pin to ground.
