PL7223
2ch Power / Energy Metering AFE Controller
OVERVIEW
PL7223 is a highly integrated power monitoring IC that measures electricity-related data for power usage measurement applications. It has built-in 2-channel ADC and a programmable DSP which can adapt to different applications such as metering, power protection and Master / Slave.
PL7223 has a built-in MTP that stores the chip configuration, DSP code and calibration data. It provides SPI interface and can be used for calibration and programming data or DSP code. MCU can be accessed through SPI interface.
PL7223 can diagnose the electricity-related data to identify overloading, short circuit, leakage current and arcing condition for further power protection features. It also provides a flexible architecture, low system BOM cost and programmable solution, to help manufacturers minimize development efforts and design a versatile and flexible product.
