Quad or More Supply Monitors
Analog Devices quad-supply supervisory circuits help simplify design due to their high accuracy, adjustable thresholds and tolerances, and a guaranteed reset signal down to an industry-leading low of 0.5 V. Most ADI supervisors exhibit ±1.5% threshold accuracy around the nominal threshold voltage—minimizing the required system voltage margin and probability of system malfunction. Voltage supervisors with pin or I2C/SMBus adjustable thresholds and tolerances provide users with maximum flexibility, which allows a single part to be used across multiple designs.
