Abstract
【解決手段】保護回路1は、外部電源端子11から供給された電圧の分圧点23の電圧を入力とするPMOS31およびPDMOS32と、PDMOS32のドレイン出力電圧を入力とするPMOS41およびPDMOS42を備える。PMOS31はPDMOS32の外部電源端子11側に接続され、PMOS41はPDMOS42の外部電源端子11側に接続される。過電圧が印加されたときには、分圧点23の電圧をツェナーダイオード22のブレークダウン電圧にクランプしてPDMOS42をオフし、過電圧が保護対象である集積回路5に供給されるのを遮断する。電圧源が逆接続されたときには、PMOS31,41の寄生ダイオードが逆バイアスされ、PMOS31,41の寄生ダイオードを通る経路に電流が流れることが阻止される。
