The invention provides an integrated chip, a system for driving a PDLC (polymer dispersed liquid crystal) dimming film by an inverter and an automobile, one integrated chip is connected between each PDLC dimming film and the inverter and is integrated with a first switch unit, a first end of the first switch unit is connected with a first input pin, a second end of the first switch unit is connected with an output pin, and a second end of the first switch unit is connected with a second input pin; the first output end of the inverter is connected with the first input pin, and the PDLC dimming film is connected with the output pin and the second output end of the inverter; and the control unit controls the first switch unit to be switched on to enable the PDLC dimming film to be connected with the inverter, or controls the first switch unit to be switched off to enable the PDLC dimming film to be disconnected from the inverter. According to the integrated chip provided by the invention, independent connection and independent control between each PDLC dimming film and the inverter are realized, and the production cost is reduced. Meanwhile, open circuit detection, over-current detection and over-temperature detection are carried out on each PDLC dimming film, and fault information is fed back to the system, so that the reliability of the system is improved.

    本发明提出一种集成芯片、逆变器驱动PDLC调光膜的系统及汽车,每个PDLC调光膜和逆变器之间连接有一个集成芯片,集成有:第一开关单元,第一开关单元的第一端连接第一输入引脚,第一开关单元的第二端连接输出引脚,逆变器的第一输出端连接第一输入引脚,PDLC调光膜连接输出引脚和逆变器的第二输出端;控制单元,控制第一开关单元导通使PDLC调光膜连接逆变器,或控制第一开关单元截止使PDLC调光膜与逆变器断开连接。本发明提出的集成芯片实现各个PDLC调光膜与逆变器之间的独立连接及独立控制,降低生产成本。同时,对各个PDLC调光膜进行开路检测、过流检测和过温检测,并将故障信息反馈至系统,提高系统的可靠性。
