Level shift circuit including a resistor configured to drive a high-withstand-voltage element |
摘要 |
In a level shift circuit for converting a level signal of several volts into a signal of a high level and transmitting the high-level signal, as a voltage reduction unit for reducing an overvoltage applied across the gate and the source of a high-withstand-voltage element used in a signal level conversion unit, a zener diode is connected between the gate and the source such that the anode of the zener diode is on the source side, so that an overcurrent is prevented from flowing in the high-withstand-voltage element.
