Abstract
An electronic circuit with suppression of high-voltage transients on the power supply line includes first and second power transistors series-connected between first and second power supplies, and first and second driving circuits for respective first and second power transistors. The first driving circuit includes a first diode and a first Zener diode, and the second driving circuit includes a second diode and a second Zener diode. Anodes of the first diode and the first Zener diode are connected to the cathode of the second Zener diode. A cathode of the first Zener diode is connected to the first power supply. A cathode of the first diode is connected to a gate of the first power transistor. Anodes of the second diode and the second Zener diode are connected together. A cathode of the second diode is connected to a gate of the second power transistor.
