Microchip has expanded its power monitoring IC portfolio with the MCP39F511, a highly integrated and accurate single-phase power monitoring IC. Designed for real-time measurement of AC power, this device combines the most popular power calculations and unique advanced features, making it ideal for high-performance commercial and industrial products such as lighting and heating systems, smart plugs, power meters and AC / DC power.
To meet industry requirements to achieve higher accuracy in current loads, higher power calculations, and event monitoring under various power conditions, the MCP39F511 power monitoring IC provides all popular standard power calculations and advanced functions. Integrated on-chip integration of active energy accumulation, four-quadrant reactive energy accumulation, zero crossing detection, and import and export of dedicated PWM outputs, and has the ability to measure active, reactive and apparent power, RMS current and RMS voltage. , Line frequency and power factor.
Allowing for more accurate power measurements, which is critical in high-performance designs, the new device has a 0.1% error over a wide dynamic range of 4000: 1. In addition, its 512-byte EEPROM allows storage of operating conditions. The MCP39F511 also includes two 24-bit delta-sigma ADCs with 94.5 dB SINAD performance, a 16-bit calculation engine and a flexible two-wire interface. In addition to the internal oscillator, a low-drift voltage reference is integrated to reduce implementation costs. This innovative combination of features and performance enables designers to add high-precision power monitoring capabilities to their end applications with minimal firmware development, reducing development time.
The MCP39F511 is available in a 28-lead 5mm x 5mm QFN package, and samples are available now for volume production. Microchip's MCP39F511 power monitor demo board (ADM00667) supports MCP39F511.
