Ok, I will try your suggestion.
About setting ENABLEn and BRAKE together sounds good, but datasheet says that after driver disabled, I have to wait at least 1 second to be able to enable it again. It is that correct?
Another question: thinking about…
Hi Evan,
Thanks for the information. Your reply did appear although it sometimes takes a few minutes to show up in the forum. If the rlock condition will be less than ~10s, the DRV8308 is an alternative. This device is similar to the DRV8307, but has…
Hi Matthew,
We don't have any completely integrated solutions for 48 V. Usually higher voltage motors are in high power applications.
You can also look at the DRV8307 and DRV8308 for an integrated hall sensored solution.
Thanks for the info. It's normal for FAULTn and LOCKn to measure 3.3V. That is the pullup voltage. The DRV8308 will pull either one Low in the presence of a fault or speed-lock.
It sounds like your problem might be due to a known issue that we uncovered…
Other Parts Discussed in Thread: DRV8308 , DRV8307 , DRV8303 , DRV8835 , DRV8837 , DRV8844 , DRV8839 Hi,
I have a request from a customer to develop a motor controller for a BLDC motor and I'm currently searching for a suitable solution. The motor is…
Hi Kevin,
Yes, you could remove the Back-EMF voltage dividers and feed hall sensor signals to the C2000. You would need to rework the C2000 firmware appropriately.
I would recommend the DRV8307/DRV8308 for a hall sensored BLDC application. They have…
Hi Jeff,
What are your current requirements for the two motors? There are several devices that may be better fits, such as the DRV8313 with integrated FETs or the DRV10983. The DRV8313 has integrated FETs but requires an external controller. The DRV10983…
Hi Zhao,
Do you know the application? BLDC gate drivers such as the DRV8301, DRV8302, DRV8303, DRV8305 plus an external mcu will work. Also the DRV8307, and DRV8308 with minimal mcu support could work.
Hi Patrick
I think it should be brushless motor application. Then,
Is it 5V or 12V application? The motor is sensored or sensorless?
I think DRV10866 / DRV11873 / DRV10975 are all possible solutions for sensorless type. And DRV8308/7 could be the…
Hi Fan,
Please take a look at the DRV8301, DRV8302, DRV8303, and DRV8305.
The devices mentioned above are similar in function but have different voltage ratings.
Also the DRV8307/DRV8308 may be a fit. These devices have a built in control loop…
