Do you know about the dual-mode power monitoring IC that maximizes system performance?

Have you heard about dual-mode power monitoring ICs to maximize system performance? In systems that use both AC and DC power supplies, implementing dual-mode power monitoring has traditionally required multiple ICs to ensure superior performance and accuracy. An increasing number of applications such as solar inverters, smart lighting and cloud servers often use dual mode to maintain safe operation, using AC as the main power source and DC as the backup power source, or vice versa.

In order to optimize performance and reduce the difficulty of developing such systems, Microchip Technology Inc. has launched a flexible dual-mode power monitoring IC that can measure AC and DC power in a range as wide as 4000:1 , the accuracy reaches industry-leading 0.1%. Integrating power calculation and event monitoring into a single IC reduces bill of materials costs and shortens firmware development time.

The MCP39F511A power monitoring IC is a highly integrated device that can meet the increasingly high power measurement accuracy requirements of high-performance designs. To simplify the calibration step and meet the extremely high requirements for accuracy, the device contains two 24-bit  analog-to-digital converters (ADCs) with a signal-to-noise ratio of 94.5 dB and a 16-bit calculation engine. Suitable for application types such as consumer, Internet of Things (IoT) and industrial applications, the MCP39F511A can automatically detect the power source type and switch between AC and DC modes to optimize measurement results. The device's on-chip EEPROM records key events to help developers troubleshoot, and the device also integrates a low-drift voltage reference and an internal oscillator to reduce costs.

Using the MCP39F511A also has the advantages of flexibility and ease of implementation. The device provides standard power calculations such as active, reactive, and apparent power, active and reactive energy, root mean square (RMS) current and voltage, line frequency, and power factor, allowing designers to High-precision power monitoring functions can be easily added to end applications. In order to further simplify development work, MCP39F511A has added many advanced functions, such as automatically saving power data to EEPROM and automatically reading power data from EEPROM when power is turned off or on, ensuring that measurement results are never lost in unexpected power outages. Event monitoring capabilities for various power conditions also improve preventive system maintenance and allow developers to better manage power consumption.

"Power monitoring is becoming increasingly common in emerging markets such as smart cities and smart homes where developers want to monitor product performance and improve energy utilization," said Bryan Liddiard, vice president of Microchip's Mixed and Linear Signal Products Group. "The MCP39F511A provides customers with A simplified development path enables customers to simultaneously monitor AC and DC power supplies with industry-leading accuracy."

This device is supported by the MCP39F511A Power Monitoring Demonstration Board (ADM00667), a full-featured single-phase power and energy monitoring system. The system can calculate and display active power, reactive power, RMS current, RMS voltage, active energy (input and output) and four-quadrant reactive energy. It can easily connect to the "power monitoring utility software" that provides automatic control functions through USB, allowing Users easily evaluate all system configuration settings.

For bulk purchases, Microchip's Application Center of Excellence can provide customized firmware devices based on customer hardware verification, helping to save verification costs and time. The above is the analysis of dual-mode power monitoring IC to maximize system performance. I hope it can be helpful to everyone.
