• Real-time Measurement of Input Power for
AC/DC supplies
• Intelligent Power Distribution Units
Description:
The MCP39F501 is a highly integrated, single-phase
power-monitoring IC designed for real-time
measurement of input power for AC/DC power
supplies, power distribution units and industrial
applications. It includes dual-channel delta sigma
ADCs, a 16-bit calculation engine, EEPROM and a
flexible 2-wire interface. An integrated low-drift voltage
reference with 10 ppm/°C in addition to 94.5 dB of
SINAD performance on each measurement channel
allows for better than 0.1% accurate designs across a
4000:1 dynamic range.
