Hi Sadashiva,
1. DRV8306 and DRV8308 are Gate driver ICs. Selection between the two depends on the wave shape of the BEMF voltage. If the BEMF voltage is sinusoidal, go for DRV8308. If trapezoidal then go for DRV8306.
2. We are developing ICs with…
Hi Adam,
Before I heard back from you I discovered that I had the hall sensors connected in the wrong sequence, basically B-A-C instead of A-B-C. I fixed this and then checked the back EMF against the hall sensor outputs. Now I have the results below…

Part Number: MCT8316Z Other Parts Discussed in Thread: DRV8316 , DRV8306 The customer would like to know the following issues:
1. O n page 21 of the data sheet, i s there a difference between PWM mode 6 and PWM mode 7 in the table PWM_MODE Configuration…
Brian,
So there's always twake after the device enters sleep mode, even on gate drivers such as DRV8306 - I saw that it had 1ms twake. if there's no products that we have that can accommodate their request its ok, I just need to let them know.
Regards…
Adam.
I have two questions.
1. Is channel 1 wavwform of the below screenshot normal?
The waveform differ from the GHA wavwform(picture 35, page32) in the DRV8306 datasheet.
2. Some motor runs normally with other driver but does not run with DRV8307…
Hey Colin,
Perfect, thanks for the clarification.
Unfortunately, our Gate Driver + Integrated Control portfolio is lacking a bit (as of 2020).
There are plenty of DRV83x devices with a simple trapezoidal algorithm which can be implemented using…
Hi Amir,
1-For the EVM you can use an external PWM frequency to drive our device. You can use up to 50KHz because that is the CSD88584Q5DC limitation. the DRV8306 can go up to 200KHz.
2- I can help to find you another one but why do you need a higher…
