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's recommended…
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 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,
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…
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 higher…
Part Number: DRV8304 Hi,
I calculate the IDRIVEP and IDRIVEP like the equation in datasheet:
Idrivep> Qgd/tr and Idriven>Qgd/tf, my mosfet has tr = 23 ns to 50 ns and Qgd 12,3 nC so IDRIVEP is ca. 0,53mA to 0,246 mA the DRV8304 has a minimum of…
Part Number: DRV8304 Hello all,
I implemented the last weeks a FOC algorithm with Matlab/Simulink and now I want to change on the hardware mode. So I want to ask if you have a suggestion about, which PWM Mode is better to be used with SVPWM Module?

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
GAIN
