Power Monitoring ICs

Power Monitoring ICs from Analog Devices provide an integrated solution for digital current and voltage measurement via an on-chip, 12-bit Analog-to-Digital converter (ADC), communicated through an I2C interface. Leveraging ADI’s precision analog design techniques, ADI’s products are twice as precise as competing devices, offering best-in-class accuracy (<±0.8%). The power monitors complete the industry’s only monitor and sequencer family to deliver <±1% accuracy for 2 to 12 supplies.

The parts are designed for today’s advanced data and telecommunications infrastructure equipment, which is driven by extremely powerful processors with ever-lower core-voltage supplies. With unprecedented accuracy, the power monitoring ICs precisely monitor processor cores to ensure they operate within voltage tolerance specifications, allowing power and system engineers to maximize system uptime and optimize system performance.
