PL7411
4ch Power/Energy Metering AFE Controller
OVERVIEW
PL7411 is a highly integrated power monitoring IC that measures electricity-related data for power usage
measurement applications. It has built-in 4-channel ADC and a programmable DSP which can adapt to
different applications such as metering, power protection and Master/Slave.
PL7411 has a built-in MTP that stores the chip configuration, DSP code and calibration data. It provides
SPI/I2C/UART interface and can be used for calibration and programming data or DSP code. MCU can be
accessed through SPI/I2C/UART interface.
PL7411 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.
