ELECTRONIC APPARATUS WITH PROTECTION CIRCUIT
First Claim
1. An electronic apparatus comprising:
- a first power source input terminal configured to receive a first driving voltage or a second driving voltage, wherein the second driving voltage is greater than the first driving voltage;
a second power source input terminal configured to receive the first driving voltage or the second driving voltage;
a protection circuit connected to the first power source input terminal;
a first voltage circuit connected to the protection circuit and driven by the first driving voltage; and
a second voltage circuit connected to the second power source input terminal and driven by the second driving voltage;
wherein the first driving voltage is transmitted to the first voltage circuit through the protection circuit while the first driving voltage is inputted to the first power source input terminal;
the second driving voltage is blocked by the protection circuit and not further transmitted to the first voltage circuit while the second driving voltage is inputted to the first power source input terminal.
