電能計(jì)量及管理

TM7780是單相多功能計(jì)量芯片，其提供高頻脈沖CF用于電能計(jì)量和高頻CF1用于指示電流有效值或電壓有效值。TM7780使用新型的防潛動(dòng)算法，只要輸入信號的功率值大于內(nèi)部的噪聲值，計(jì)量模塊則開始正確計(jì)量。本產(chǎn)品性能優(yōu)良，質(zhì)量可靠。 \n\n\t? 5V單電源供電，工作電流小于3mA\n\n? 內(nèi)置電源檢測電路，當(dāng)電源電壓低于4V時(shí)，芯片進(jìn)入復(fù)位狀態(tài)\n\n? 內(nèi)置振蕩器頻率約為3.579MHz，電源電壓抑制比<0.01/V\n\n? 高頻脈沖CF，指示有功功率，滿足50/60Hz IEC 687/1036標(biāo)準(zhǔn)的準(zhǔn)確度要求，在1000:1范圍內(nèi)達(dá)到±0.2%的精度\n\n? 高頻脈沖CF1，可配置成為輸出電流有效值或電壓有效值，在500:1的范圍內(nèi)達(dá)到±0.5%的精度\n\n? 封裝形式：SOP8;
