"The MCP39F511 power-monitoring IC is an ideal complement to Microchip's successful energy measurement portfolio," said Bryan J. Liddiard, marketing vice president of Microchip's Analog and Interface Products Division. "We listened to our customers' feedback and added the most requested features to better support engineers in their next generation of designs, including power-hungry applications such as data centers and advanced applications such as smart energy and the growing Internet of Things."
To address industry requirements for better accuracy across current loads, additional power calculations, and event monitoring of various power conditions, the MCP39F511 power-monitoring IC provides all of the popular standard power calculations combined with advanced features. The import and export of active energy accumulation, four-quadrant reactive energy accumulation, zero-crossing detection and dedicated PWM output have now been integrated on-chip, along with 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 to higher-performance designs, this new device is capable of just 0.1 % error across a wide 4000:1 dynamic range. Additionally, its 512 bytes of EEPROM allow operating-condition storage. The MCP39F511 also includes two 24-bit delta-sigma ADCs with 94.5 dB of SINAD performance, a 16-bit calculation engine, and a flexible two-wire interface. A low-drift voltage reference, in addition to an internal oscillator, is integrated to reduce implementation costs. This unique combination of features and performance allows designers to add highly accurate power-monitoring functions to their end applications with minimal firmware development, speeding development time.
Development Support
The MCP39F511 is supported by Microchip's MCP39F511 Power Monitor Demonstration Board (Part # ADM00667), which is available now for $150 via any Microchip sales representative or authorized worldwide distributor, or from microchipDIRECT(http://www.microchip.com/microchipDIRECT-042115a).
Pricing & Availability
The MCP39F511 is available now for sampling and volume production, in a 28-lead, 5x5 mm QFN package. It is priced at $1.82 each, in 5,000-unit quantities. For additional information, contact any Microchip sales representative or authorized worldwide distributor, or visit Microchip's Web site at http://www.microchip.com/MCP39F511-042115a. To purchase products mentioned in this press release, go to microchipDIRECT or contact one of Microchip's authorized distribution partners.
