Extended Temperature Range -40°C to +125°C
Applications:
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.

3: VIN = 1VPP = 353 mVRMS @ 50/60 Hz.
4: Applies to Voltage Sag and Voltage Surge Events Only.
5: Variation applies to internal clock and UART only. All calculated output quantities are temperature compensated to the
performance listed in the respective specification.
6: Applies to all gains. Offset and gain errors depend on the PGA gain setting. See Section 2.0 “Typical Performance
Curves” for typical performance.
7: N = Value in the AccumulationInternalParameter register (0x005A). The default value of this register is 2 or T CAL = 80 ms
