The ADE9178 is a high accuracy, 3-phase electrical energy measurement IC primarily for the electric vehicle supply equipment (EVSE) market with serial peripheral interface (SPI) and two flexible pulse outputs. The ADE9178 can in- terface with up to four daisy-chained ADE9113/ADE9112/ADE9103 devices through SPI protocol. The ADE9178 incorporates all the signal processing required to perform total active energy, apparent energy measurements, and root mean square (RMS) calculations. A fixed function DSP executes this signal processing. The ADE9178 is well-suited for the EVSE market due to its broad feature set such as protective earth and neutral (PEN) open fault detection without the need for any additional hardware, overcurrent, and overvoltage detection using RMS of half cycle/one cycle and vehicle to grid/home (V2X) capabilities. The ADE9178 measures active and apparent energy in various 3-phase configurations, such as wye or delta services, with both three and four wires, single phase, and split phase while supporting both 50 Hz and 60 Hz line frequencies. The ADE9178 provides gain, offset, and phase calibration features for each ADC channel. The CF1 and CF2 logic outputs provide power information that is proportional to the measured accumulated energy. The ADE9178 incorporates some basic power quality measurement features, such as short-duration undervoltage/undercurrent or over- voltage/overcurrent detection, line voltage period measurements, and angles between phase voltages and currents. A Host microcon- troller unit (MCU) can be used to communicate with the ADE9178 through 4-wire SPI. Waveform streaming can be accessed by the Host MCU through the WAVEFORM_TX pin of the ADE9178. The ADE9178 also has four user-programmable interrupt pins, IRQ0, IRQ1, IRQ2, and IRQ3, to indicate that an enabled interrupt event has occurred. The ADE9178 is available in a 40-lead, LFCSP package. For more details on how to setup the ADE9178 in an EVSE application, refer to the application note Using ADE9178 for EV Charger Metrology Solution. |
