Current/Power/Energy Monitor ICs

Systems designers know that before they can manage power, they first need to measure it. These power monitoring ICs measure power, voltage, current, zero cross detection and energy accumulation.

For DC power monitoring from 0 to 40V, our high-side current sensors include an I2C that is perfect for embedded computing, networking, industrial and artificial intelligence. To get ahead of the thermal curve, we also offer several devices integrating both current and temperature sensors.

For AC and energy monitoring, Microchip offers single-phase and poly-phase power measurement solutions to tackle the evolving needs of energy management. Our portfolio, derived from many years of innovation in the utility metering and Switch Mode Power Supply (SMPS) markets, includes solutions ideal for smart metering, switch mode power supplies, intelligent lighting and smart building applications.
