The ADM8612 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. A separate supply input allows the ADM8612 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 ADM8612 can reset on demand through the manual reset input.

The ADM8612 are available in a 6-ball, 1.46 mm × 0.96 mm WLCSP. The ADM8612 are specified over the temperature range of −40°C to +85°C.
