DRV10970: SENSORED BLDC MOTOR DRIVER

DRV10970: DRV10970

Hello
When we look at the TIDUBH6 file, it seems that 3 single-output hall sensors are used. However, 6 signals, positive and negative, are input to the driver IC. What is the reason of this? How is it?

    Hi Enes,

    TIDUBH6 refers to the TIDA-00919 where we have the Hall ICs but the connectors are not part of this. These connectors are part of DRV10970EVM. 

    If the Hall is a digital sensor, we connect HP of all three phases to the IC and HN is pulled to VINT/2. If the hall is analog, we connect all 6 signals from the Hall to the IC. 

    Regards,
