Product Details

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 in the data sheet. 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. Not all device options are available as standard models.

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.
