The MCP39F501-E/MQ is a single-phase, Power-monitoring IC with calculation and event detection. 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 addition to 94.5dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
- Power monitoring accuracy capable of 0.1% error across 4000:1 dynamic range
- Fast calibration routines
- Programmable event notifications such as overcurrent and voltage sag, surge protection
- 512-byte User-accessible EEPROM through page read/write commands
- Non-volatile on-chip memory, no external memory required
- Built-in calculations on fast 16-bit processing core- active, reactive and apparent power
- Two-wire serial protocol using a 2-wire UART interface supporting multiple devices on a single bus
- Low-drift internal voltage reference, 10ppm/°C typical
