Post Date: 2018-09-08, Microchip Technology
Microchip Technology has introduced a flexible dual-mode power monitoring IC that measures AC and DC modes with an industry-leading 0.1% accuracy over a wide range of 4000: 1. A single IC comes with power calculations and event monitoring, which reduces bill of materials costs and firmware development time. The MCP39F511A power monitoring IC is a highly integrated device that meets the growing demand for more accurate power measurements in high-performance designs. As developers want to monitor product performance and improve energy use, power monitoring has become increasingly common in expanding markets such as smart cities and smart homes. To simplify the calibration process and meet most accuracy requirements, two 24-bit delta-sigma ADCs with 94.5 dB SINAD performance and a 16-bit calculation engine are included. The IC is well-suited for a variety of consumer, IoT and industrial applications and can automatically sense the type of power supply and switch between AC and DC modes to optimize measurement results. The device can also help developers troubleshoot issues using on-chip EEPROM to record fault events, Other benefits of using ICs include flexibility and ease of implementation. This device provides standard power calculation functions such as active, active and reactive power, reactive and apparent power, line frequency and power factor, root mean square (RMS) current and voltage, allowing designers to easily integrate high accuracy Power monitoring capabilities are added to the final application without the need for minimal firmware development.
