Vishnu san Thank you for your update.
Vishnu Balaraj said: As Brian mentioned the gain and advance values get latched during powerup and this can cause the performance difference at 16V and 24.
->OK, we got it. The customer checks this using their system…
Part Number: DRV8308 Other Parts Discussed in Thread: DRV8307 Hi all Would you mind if we ask DRV8308? Could you let us know the LOCKn assert condition(LOCKn=Low)? The datasheet shows "After a constant speed is reached, the LOCKn pin is pulled low and only…
Part Number: DRV8308 Hi team,
I am using DRV8308 to control a brushless motor. The rotation of the motor is controlled by "Clock Frequency Mode". I am inputting a 150Hz square wave to CLKIN, but the rotation of the motor is not so stable. In such…
Part Number: DRV8308 Hi team,
My customer want to know the time from the motor driver recieved SPI signal to motor drive operation.
In customer use case, they are using following sequence,
0 rpm to 800 rpm -> 800 rpm for 0.5s -> 800rpm to 3000 rpm -…
Part Number: DRV8308 We are considering using the DRV8308 gate driver to drive a 3 phase BLDC motor as it is sensored and controls the motor sinusoidally. Am I correct in saying the speed can be controlled by either, CLOCK FREQUENCY MODE changing the frequency…
Part Number: DRV8308 Other Parts Discussed in Thread: MCT8316A , MCF8316A hi team:
My customer feedback that after the software corresponding to the EVM board of the motor driver chip is opened, it fails to modify the SPDMODE setting after opening the All…
Hi Aaron
Aaron Barrera said: But for the variation in blower, you may need to re-tune the DRV8308 for this new blower if there are different resistance/inductance characteristics
Yes sure I will consider the above while using a new blower.
Thankyou

Part Number: DRV8308 Good day,
We are developing a light vehicle using the DRV8308. it has performed well so far,except for..
The lock pin, initially I assumed it goes low when the clkin frequency matched the fgout frequency but that doesn't seem to be…
Part Number: DRV8308 Hi team,
When a "1 second" momentary power failure occurs during motor rotation, then just after that(1sec later) I try to set the registers again via SPI to restart the motor. However, register setting is not possible. …
