Part Number: DRV8350R
Tool/software:
Hello! Dear. TI Team,
We are currently using the DRV8350RH gate driver IC and are experiencing two issues.
We have configured the MOSFETs for driving a 3-phase motor as shown below, and we are applying a snubber…
Hello Thomas,
Yes, the DRV8353 can be used for servo drives. In fact we made a reference design with the title "48V/500W Three-phase Inverter with Smart Gate Driver Reference Design for Servo Drives" https://www.ti.com/tool/TIDA-01629
The design uses…
Part Number: C2000WARE-MOTORCONTROL-SDK Other Parts Discussed in Thread: DRV8350
We are trying to make a BLDC motor controller using the instaspin-FOC software with the fast observer. We are facing an issue where we start to lose control of the motor…
Part Number: DRV8320 Other Parts Discussed in Thread: DRV8350
Hi, TI support.
The issue is found while using DRV8320H on my 20V platform 6 months ago. When no FET switching, all three phase node voltages rising up to B+, rising form 0 to B+ takes…
Hey Tess,
The sensorless FW is designed to use either current sense feedback or BEMF to estimate the position of the motor. The sensored FW instead has to parse that position information from the hall sensors. They are fundamentally different and…
Hi NY,
nFAULT itself does not have a deglitch time as it is not a fault monitor
the various fault types reported by this nFAULT pin, however, may have deglitch timers depending in the fault category
see this example below from the datasheet for…
Part Number: DRV8350R Other Parts Discussed in Thread: DRV8350 , CSD19536KTT , TIDA-010056 Hello,
I have designed a BLDC controller with DRV8350RH and after building up multiple PCBs, I am finding that the low-side MOSFET on Phase C is consistently…
Hello Chandu,
it looks you are using a 48V DC-link voltage . IGBT are typically used for DC-link voltages 320V DC and higher.
At 48V DC with a PWM switching frequency of 8 kHz to 16 kHz (equivalent to what is typically used with IGBTs) we rather see…
Hi user4708725 ,
The closest schematic is the block diagram (Figure 2) of the application report.
The driver block used was a 6x PWM gate driver.
There are several devices that can be used for the driver. Examples of 6x PWM devices include the DRV8301…
Hello Elavarasan,
I noticed that you're asking a lot about commutation and algorithm design theory rather than "how can the DRV83x or MSPx enable the algorithm I'm trying to create". Algorithm creation is not trivial and companies spend a lot of money…
