Power/Current Monitors

Systems designers know that before they can manage power, they first need to measure it.   These power monitoring ICs measure power, voltage and current, while providing the calculated power over an I2C interface.

Power consumption figures into cost of ownership for many industries: networking, communication, and computing.  By means of active configuration over the I2C, these power monitors can help conserve power.  With this in mind, systems can be designed for lower or higher power, voltage, and current case scenarios.

These I2C power monitors are based on the traditional high-side current sensor.  The current monitors can measure voltage rails from 0V to 40V.  Several of the devices also come with temperature sensors for where we see high power we need thermal management.
