Product Description

CYP1840 Built-in Clock, Calibration Free, Single Phase Energy Meter IC with Integrated Oscillator

DESCRIPTION:
CYP1840 is a built-in clock and calibration-free energy metering IC, suitable for single-phase multifunctional electricity meter, smart socket, smart home appliances, electric bicycle charging pile and other applications with better cost performance.
CYP1840 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.
CYP1840 can measure electric parameters such as current and voltage RMS, active power, active energy, fast current RMS (for leakage detection/over-current protection), and temperature detection, waveform output and so on. CYP1840 output data through the UART/SPI interface. It is available for the smart socket, smart appliances, single-phase multi-function power meter, electric bicycle charging pile and information requirement of data acquisition in electricity applications.
CYP1840 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.
