GENERAL DESCRIPTION
The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615
are voltage supervisory circuits that monitor power supply voltage
levels and code execution integrity in microprocessor-based
systems. Apart from 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 through a manual reset input.
The ultralow power consumption of these devices makes them
suitable for power efficiency sensitive systems, such as battery-
powered portable devices and energy meters.
The features of each member of the device family are shown in
Table 9. Each device subdivides into submodels with differences
in factory preset voltage monitoring threshold options. In the
range of 2 V to 4.63 V, 10 options are available for the ADM8611.
In the range of 2.32 V to 4.63 V, five options are available for

both the ADM8613 and ADM8614. A separate supply input
allows the ADM8612 and ADM8615 to monitor 20 different
low voltage levels from 0.5 V to 1.9 V.
The ADM8611, ADM8612, ADM8613, and ADM8615 can
reset on demand through the manual reset input. The watchdog
function on the ADM8613, ADM8614, and ADM8615 monitors
the heartbeat of the microprocessor through the WDI pin. The
ADM8613 and ADM8614 have a watchdog disable input, which
allows the user to disable the watchdog function, if required. The
ADM8614 also has a watchdog timeout extension input, allowing
the watchdog timeout to be extended from 1.6 sec to 100 sec.
The ADM8611/ADM8612/ADM8613/ADM8614/ADM8615
are available in a 6-ball, 1.46 mm × 0.96 mm WLCSP. These
devices are specified over the temperature range of −40°C to +85°C.
