Current/Voltage/Power Monitor ICs

Systems designers know that before they can manage power, they need to measure it. Our power monitor ICs measure power, voltage, current and energy accumulation. For power monitoring from 0 to 40V, our high-side current sensors include an I2C interface that is perfect for embedded computing, networking, industrial and artificial intelligence. To get ahead of the thermal curve, we also offer several devices that integrate both current and temperature sensors.

Key Benefits of Our Power Monitoring Solutions

  • Calculate power, reducing host code overhead
  • Require no filter circuits, saving circuitry costs
  • Sampling up to 2 seconds to deliver a better understanding of power consumption
