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

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 sensors…
Part Number: DRV8304 Hi,
I have a question about the Synchronous and Asynchronous mode in 1xPWM.
I use 10% Duty Cycle and Asynchronous mode but I cannot see the PWM Signal in SHX Pin. Is always HIGH. An other Question is why I have this ramp in the…
Part Number: DRV8304 Other Parts Discussed in Thread: DRV8308 Hi,
I use the DRV8304 to 1xPWM Mode Asynchronous and I use the following code to change every 500ms between state 1 -> 2 and 2 ->1:
__HAL_TIM_SET_COMPARE(&htim4,TIM_CHANNEL_1,(uint16_t…
Part Number: DRV8304 Hi,
could someone explain me what is the diffirent between uni and bidirectional sense operation and in which application make sense to use the this two operations?
King regards,
