Part Number: DRV8304 Other Parts Discussed in Thread: DRV8350 , Hello,
I would like to know how much difference the DRV8304 (and DRV8350) can take between the VM that goes to MOSFETs and the VM that goes into other pins of the IC.
I realise that it…
Part Number: DRV8304 Hi team,
I want to know how AUTOCAL works? After AUtoCAL started, what kind of operation did the op amp perform? (In addition to connecting the input to ground), how do we perform the calibration? (Adjusted the internal resistance…
Part Number: DRV8304 Hi,
I am running my DRV8304S on 1x PWM mode.
The phase waveform is a perfect trapezoid when DIR=0 (INHC input). When DIR=1, the waveform looks like this:
As you can see, there are some stray PWM signals in between the trapezoids…
Part Number: DRV8304 Hi.
We have a product for an electric wheelchair.
We do not necessarily want to do regenerative breaking, but when going downhill, the chair will make the motor turn... so if we go fast enough, the motor will generate a voltage…
Part Number: DRV8304 Hi,
We are using the DRV8304H in 1xPWM mode and on a new spin of the board the DRV8304H appears to be coming up in 6xPWM modDRVe instead. The only output phase showing any PWM signal is GHA corresponding to INHA. Previous versions…

As far as i understood from ti drv8304 boost has discontinue.
Is there any new EVM for that drv?
Does the drv8304 has finish the development. It is in preproduction step but cannot be purchased.
I spoke with ryan last october while he visit…
Part Number: DRV8304 Hello Guys,
I am designing a BLDC motor driver with DRV8304. If i dont want inbuild current sense of DRV8304 what shall i do with following pins.
SOx
SPx
SNx
VREF
CAL

Part Number: DRV8304 Hi,
I have solved the last days some issues with SPI communication and the last days I made the first attempt to connect a motor to my PCB. But it is not working and I attached the oscilloscope on SHB and SHC.
I fake the Hall…
