PL7211数据手册Prolific中文资料规格书

描述 Description

OVERVIEWPL7211 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.
PL7211 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.
PL7211 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.
