Microchip MCP39F511 Single-Phase Power-Monitoring ICs

The MCP39F511 is a highly integrated, complete single-phase power-monitoring IC designed for a large range of applications from home automation to industrial lighting.

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 94.5 dB of Signal-to-Noise Ratio and Distortion performance on each measurement channel allows for better than 0.1% accurate designs across a 4000 to 1 dynamic range.

The fast 16-bit processing core features built-in calculations with active, reactive and apparent power, true RMS current and voltage as well as line frequency and power factor.

The MCP39F511 has a dedicated PWM output pin with programmable frequency and duty cycle, zero crossing deduction pin output, and an automatic event pin control through fast voltage surge detection that is less than 5 milliseconds.

With an extended temperature range from -40°C to 125°C and housed in a small 28-lead 5x5 QFN package, the MCP39F511 is ideal in power monitoring for home automation, industrial lighting, the real-time measurement of input power for power supplies, and intelligent power distribution units.
