Product Description

CYP1842 Built-in Clock Calibration Free Single Phase Energy Meter IC with Integrated Oscillator

DESCRIPTION:
CYP1842 is a built-in clock calibration-free energy metering IC, which is suitable for single-phase multi-function electricity meters, smart sockets, smart home appliances and other applications, with more cost-efficient solution.
CYP1842 integrates 2 high-precision Sigma-Delta ADC to measure current and voltage simultaneously. Reference voltage, power management and other analog circuit modules, and processing active power, current and voltage RMS electrical parameters digital signal processing circuit.
CYP1842 can measure electric parameters such as current and voltage RMS, active power, active energy, fast current RMS (for over-current protection), and waveform output and so on. CYP1842 output data through the UART/SPI interface. It is available for the smart socket, smart appliances, single-phase multi-function power meter and information requirement of data acquisition in electricity applications.
CYP1842 has a patented anti-creep design, which can be combined with reasonable external hardware design to ensure that the noise energy cannot be calculated in the energy pulse when there is no load.


FEATURES:
