PL7223 Product Brochure

V1.0 6/17/2015

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.
