Part Number: DRV8424 Hi team,
I received some questions. Customer is concerned about are there any problems with the way using the device following.
Could you support these please?
If the fault pin is not used, is it OK to go directly to GND?
When power…
Part Number: DRV8425 Other Parts Discussed in Thread: DRV8424 Hi team,
Limit of VREF are different DRV8424 and 5.
Does this mean that the rated current is different for 2.5A and 2.0A, but the internal circuitry of VREF is the same?
Also, if used beyond…
Part Number: DRV8424 Other Parts Discussed in Thread: DRV8462 Hi Team,
When designing, the customer planned to isolate the motor power supply and logic chip power supply. This chip contains the ground PGND on the motor side and the ground GND of the device…
Part Number: DRV8424 Hi team,
The DVDD pin voltage of this device was measured to be 0. DVDD is also 0 if the stepper motor is not connected. Customer referred to the design in the data sheet. The following is the schematic diagram of the design.
Could…
Part Number: DRV8424 Hi support team.
My customer has a 100Ω connection between PGND and GND. I'm not sure if this is the cause, but I'm having issues with multiple devices becoming corrupted. We are currently investigating whether there are…
Part Number: DRV8424 As the product has the requirement of Atmospheric pressure and Installation altitude, so I need to check if the part applied meet this requirement.
Part Number: DRV8424 Hi Team,
The DRV8424RGER drive chip is controlled to spin the drive motor using the STM32F302RBT6 monolithic.
Initialize the GPIOs of the DRV8424 as follows:
MX_DRV8424_GPIO_Init(); //PC10 close interrupt STEP_TOFF(0); //Modify 1/8 …
Part Number: DRV8424 Other Parts Discussed in Thread: DRV8462 , Hi Sir,
My customer is testing Drv8424 and drv8462 evm by using their ASIC with nSLEEP 、 ENABLE 、 DIR 、 STEP 、 M1 、 M0 and VREF. Testing DRV8462 evm is ok, but controlling DRV8424 evm has problem: can…
Hi Higa-san,
Top (red) - waveform/diagram. The bump can also appear in this place, energy from regeneration from phase B is causing a bump because only slow decay is used or not enough of fast decay. Red diagram shows driving phase not a slow decay.
