Overview

NCP81232 は DrMOS パワー・ステージで動作するようにシングルまたはデュアル出力レギュレータとして構成できます。この IC は、最大 8 つの固有の出力構成で設定でき、単一相から 4 相までの動作を備えた単一出力として、または 3 + 1、2 + 2、2 + 1、および 1 + 1 の位相の組み合わせを備えたデュアル出力デバイスとして動作します。このコントローラにより差動電流センスと電圧センスの精度が高くなります。DCR 電流センスをサポートし、または DrMOS からの IMON 信号にも対応できます。このパーツには過電流、過/低電圧からの保護に加え、過熱保護もあります。
