ADE7752B: 三相、三线和四线电能计量IC，内置脉冲输出

ADE7752B 功能框图 ADE7752B*是一款高精度、三相电能计量IC。该器件的技术规格超越了IEC62053-21标准所列的精度要求。ADE7752B唯一采用的模拟电路是模数转换器（ADC）和基准电压源电路。所有其他信号处理（例如，乘法、滤波和求和）都在数字域中实现。这种方式能够始终在极端环境条件下提供出色的稳定性和精度。ADE7752B在低频输出F1和F2上提供平均有功功率信息。上述逻辑输出可用于直接驱动机电计数器或与微控制器（MCU）接口。CF逻辑输出提供瞬时有功功率信息。该输出设计用于校准。ADE7752B在VDD引脚上有一个电源监控电路。在VDD上的电源电压达到4 V之前，器件处于无效状态。如果电源电压降至4 V以下，ADE7752B复位并且F1、F2和CF上不发出脉冲。内部相位匹配电路确保电压和电流通道相位匹配。内部空载阈值确保空载时ADE7752B不会出现爬电现象。ADE7752B采用24引脚SOIC封装。

The ADE7752B* is a high accuracy polyphase electrical energy measurement IC. The ADE7752B specifications surpass the accuracy requirements as quoted in the IEC62053-21 standard. The only analog circuitry used in the ADE7752B is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (for example, multiplication, filtering, and summation) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.The ADE7752B supplies average active power information on the low frequency outputs, F1 and F2. These logic outputs can be used to directly drive an electromechanical counter or to interface with a microcontroller (MCU). The CF logic output gives instantaneous active power information. This output is intended to be used for calibration purposes.The ADE7752B includes a power supply monitoring circuit on the VDD pin. The ADE7752B remains inactive until the supply voltage on VDD reaches 4 V. If the supply falls below 4 V, the ADE7752B resets and no pulses are issued on F1, F2, and CF.Internal phase matching circuitry ensures that the voltage and current channels are phase matched. An internal no load threshold ensures that the ADE7752B does not exhibit any creep when there is no load.The ADE7752B is available in a 24-lead SOIC package.
