产品概述 返回TOPWVT嘉泰姆

The CXDR75132 is a highly integrated IC for simplified implementation of single-phase AC power measurement into power supplies, smart appliances, and other applications with embedded AC load monitoring and control. It is packaged in a small, 5mm x 5mm, 32-pin QFN package for optimal space savings. At the measurement interface, the device provides four analog inputs for interfacing to voltage and current sensors. Voltages from the sensors are fed to our Single Converter Technology that uses a 22-bit delta-sigma ADC, independent 32-bit compute engine (CE), digital temperature compensation, and precision voltage references to provide better than 0.5% power measurement accuracy over a wide 2000:1 dynamic range. The integrated MPU core and 32 KB of flash memory provides a flexible means of configuration, post-processing, data formatting, and interfacing to any host processor through the UART interface and/or DIO pins. Complete application firmware is available and can be preloaded into the IC during manufacturing test. Alternatively, a complete array of ICE, development tools, and programming libraries are available to allow customization for each application
