ADM8642 Ultralow Power Voltage Detector with Disable Input and Low Threshold Voltages
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 4.6 V3 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.
