Part Number: DRV8328 Tool/software: We are using a drv8328 gate driver for our 12V BLDC motor rated at 10A max, and we are facing the issue of the rotation of the motor.
Can anyone give us the logic of rotation for the 3-phase BLDC motor?
Part Number: DRV8328 Tool/software: Hello team,
When VDSLVL is tied to 100kΩ, VDS overcurrent protection is "disable completely" or "just set large reference threshold"? We are concerned about large pulse voltage when motor starts…
Sakai-san,
There are two specifications in the datasheet.
Tds_BLK - VDS overcurrent protection blanking time
Tds_DG - VDS overcurrent protection deglitch time
The blanking time is the period after the FET is commanded to switch to the ON state. This is…
Part Number: DRV8328 Tool/software: Hello team,
My customer is considering the below usage. What do you think?
GVDD is connected to external load (~10mA)
FET (for motor) and external load driving do not do at the same time.
Best regards,
Shotaro
Part Number: DRV8328 Tool/software: I am bringing up a new design using the DRV8328 and running into an issue with certain setups that will cause the MOSFETs to burn.
I thought this was due to the switching times being too fast, so I increased the gate…
Part Number: DRV8328 Tool/software: Hello, I am using the DRV8328A with the DT resistor set to 100k. Based on this, my dead time should be 550ns minimum. I have verified the resistor measures 100k and the firmware is set to a dead time of 416ns. The…
Part Number: DRV8328 Tool/software: I have a DRV8328A design that is working well with complementary PWM on. About 1/3 of the units are unable to spin a motor with complementary pwm turned off.
I have played around with the gate resistors and bootstrap…
Hello,
Please post this as a new E2E question as this thread has been closed for some time. Please provide a bit more information on your set up when you do post the question.
