GENERAL DESCRIPTION
The ADM8641 and ADM8642 are simple voltage detectors
suitable for use in general-purpose applications. 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 factory preset detection thresholds from 0.5 V to 4.63 V
with ±1.2% accuracy over the full temperature range enable the
devices to monitor the node of interest accurately with direct
contact. The DIS input lets the user hold the output low
regardless of the state of the input.

The ADM8641 monitors the voltage using the VCC pin. The
separate supply pin on the ADM8642 allows it to have a lower
detection threshold down to 0.5 V.
The ADM8641 and ADM8642 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.
