Part Number: DRV8706-Q1

使用DRV8706S控制车门电机，SPI、PWM输出正常，但是GH1、GH2输出12V，GL1、GL2输出0V，电源是12V供电，四个MOS管没有导通。

    Hey Eden,

    Please give our device expert a day or two to get back to you.  If you could post some labelled waveforms and some more details that would be helpful.  What mode are you running - PWM, PH/EN, or half-bridge control?  

    Translation: Using DRV8706S to control door motor, SPI, PWM outputs are normal, but GH1, GH2 output 12V, GL1, GL2 output 0V, 12V supply, the four MOS tubes are not conducting.

    Hey Eden, 

    Do you have a DRV8706-Q1EVM you can test this with to compare? 

    An can you post labelled waveforms of this and schematic? 

    Best,

    Jacob
