    摘要: 【課題】電源の逆接時に流れる電流を確実に遮断する。 【解決手段】駆動装置1は、直流電源2から負荷3へと至る電源供給経路に直列に介在するものであり且つ互いの寄生ダイオードが逆向きとなるように接続されたトランジスタQ1およびQ2の駆動を制御する。駆動装置1は、駆動部5および逆接保護制御部6を備える。駆動部5は、直流電源2の高電位側端子に接続される電源線L1および直流電源2の低電位側端子に接続される電源線L2を介して電源供給を受けて動作するものであり、トランジスタQ1、Q2を駆動する。逆接保護制御部6は、電源線L1、L2の電位関係が正常の関係とは逆転した関係になると、駆動部5による駆動に関係なくトランジスタQ2を強制的にオフ駆動して電源供給経路に流れる電流を遮断する保護動作を実行する。 【選択図】図1

    摘要: PROBLEM TO BE SOLVED: To prevent an excessive current from flowing through a protection device, and also to prevent latch-up. SOLUTION: A surge protection circuit includes a surge detection circuit 14 for detecting a surge applied to a semiconductor integrated circuit, and the protection device 15 for absorbing the surge. The protection device is arranged between a signal terminal for inputting a signal to the semiconductor integrated circuit and a power source terminal for supplying a power source voltage. When the surge detection circuit does not detect any surge while the power source voltage is not larger than a voltage enough to normally operate the semiconductor integrated circuit, the protection device is set in a current limiting state, and when the surge detection circuit detects a surge while the power source voltage is not larger than a voltage enough to normally operate the semiconductor integrated circuit, the protection device is set in a current non-limiting state.
