Solid-state switch driving circuit for vehicle

A solid-state switch driving circuit for a vehicle, comprising:

• an oscillation circuit configured to generate square waves having a specific width;
• a constant voltage circuit configured to supply constant voltage to the oscillation circuit;
• a first Field Effect Transistor (FET) (129) connected to an output of the oscillation circuit, and configured to have a drain connected to a battery via a resistor (123) and a source grounded and configured to output the square waves in response to output of the oscillation circuit;
• a second FET (113) configured to have a gate connected to output of the first FET (129) and to be selectively turned on and off by the first FET (129);
• a third FET (115) configured to have a gate connected to the drain of the first FET (129) and a drain connected to a drain of the second FET (113) and to output an output opposite to an output of the second FET (113) and to be selectively turned on and off by the first FET (129);
• a first time constant circuit connected to the drain of the second FET (113) and the drain of the third FET (115), and configured to have one side connected to the battery via a reverse voltage protection diode (101);
• wherein the reverse voltage protection diode (101) is configured to have an N pole connected in series to the first time constant circuit and a P pole connected to the battery;
• a solid-state power switch (117) configured to have a drain connected to the battery and a source connected to a load, and configured to selectively turn on and off power applied to the load;
• and
• a second time constant circuit configured to have one side connected to the first time constant circuit and the reverse voltage protection diode (101), another side connected to a gate of the solid-state power switch (117), and yet another side grounded.
