SSP1839
SSP1839 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.
SSP1839 integrates 3 high-precision sigma-delta ADC, it can measure two channel of current and one channel of voltage simultaneously.
SSP1839 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. SSP1839 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.
SSP1839 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.
