DRIVE CIRCUIT FOR AN ELECTRO-OPTIC REARVIEW MIRROR SYSTEM |
| 摘要 |
An electro-optic rearview mirror system is provided. The electro-optic rearview mirror system includes an inside electro-optic rearview mirror element and an outside electro-optic rearview mirror element in series with the inside electro-optic rearview mirror element. A drive circuit is in electrical communication with the inside electro-optic rearview mirror element and the outside electro-optic rearview mirror element and includes a first power operational amplifier and a second power operational amplifier, both of which are configured as voltage followers. The drive circuit is configured to apply overvoltage to the inside electro-optic rearview mirror element if the outside electro-optic rearview mirror element is shorted. |
