Zusammenfassung:	To obtain a semiconductor device with smaller mounting area and lower cost.SOLUTION: P-side switching elements SP1, SP2, SP3 and N-side switching elements SN1, SN2, SN3 connected to form a half bridge are driven by N-side drive circuits DCN1, DCN2, DCN3 and P-side drive circuits DCP1, DCP2, DCP3 respectively. The N-side power generation circuit PGN1, PGN2, PGN3 generates the power supply voltage for the N-side drive circuit DCN1, DCN2, DCN3 from the power supply voltage of the P-side switching element SP1, SP2, SP3.SELECTED DRAWING: Figure 1 【課題】実装面積を小さくし、コストを低減することができる半導体装置を得る。【解決手段】ハーフブリッジを構成するように接続されたＰ側スイッチング素子ＳＰ１，ＳＰ２，ＳＰ３及びＮ側スイッチング素子ＳＮ１，ＳＮ２，ＳＮ３をＮ側駆動回路ＤＣＮ１，ＤＣＮ２，ＤＣＮ３及びＰ側駆動回路ＤＣＰ１，ＤＣＰ２，ＤＣＰ３がそれぞれ駆動する。Ｎ側電源生成回路ＰＧＮ１，ＰＧＮ２，ＰＧＮ３がＰ側スイッチング素子ＳＰ１，ＳＰ２，ＳＰ３の電源電圧からＮ側駆動回路ＤＣＮ１，ＤＣＮ２，ＤＣＮ３の電源電圧を生成する。【選択図】図１
