CategorySemiconductors => Power Management ICs => 8829925
TitleCurrent & Power Monitors & Regulators Sing-Phase PwrMon IC w/Calc, Energy Accum
Description

Microchip MCP39F511 Single-Phase Power-Monitoring IC is designed for real-time measurement of input power for AC/DC power supplies, providing power and energy values. The MCP39F511 includes dual-channel delta sigma ADCs, a 16-bit calculation engine, EEPROM, and a flexible 2-wire interface. An integrated low-drift voltage reference in addition to the 94.5dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.

MCP39F511 Typical Application Single Phase, Two-Wire Application Schematic

Note 1: The MCP39F511 demonstration board uses a switching power supply, however a low-cost capacitive-based supply, as shown here, is sufficient for many applications. 2: The external sensing components shown here, 2 m shunt, two 499 k and 1 k resistors for the 1000:1 voltage divider, are specifically chosen to match the default values for the calibration registers defined in Section 6.0 "Register Descriptions". By choosing low-tolerance components of these values (e.g. 1% tolerance), measurement accuracy in the 2-3% range can be achieved with zero calibration. See Section 9.0 "MCP39F511 Calibration" for more information.
