Part Number: DRV8839EVM Other Parts Discussed in Thread: DRV8839 I am driving and inductive load wth the DRV8839EVM board at 125kHz. At the output transition from Low to High I measure a dead time of at least 400ns, whil at the transition from High to…
Part Number: DRV8839EVM Other Parts Discussed in Thread: DRV8839 Hi Sirs, Would you please advise that if we can use 5V VM and 1.8V VCC, while the test conditions on the datasheet is 3.3V VCC? Thank you and Best regards, Wayne Chen 12/22/2017
Other Parts Discussed in Thread: DRV8839EVM , DRV8839 Hi
I have just bought the DRV8839EVM, I would kite to change the code.
My question is, where do I find the firmware preloaded on the board ?
Thanks

Hi Bruno,
Thank you for the additional information.
In the original design with no bulk capacitor and VM and VCC effectively shorted, it is likely the device was being damaged because the VCC voltage was exceeding the absolute maximum voltage.

First you need to know what motor size you need 10, 100 or maybe even 200 Amp, then select the proper driver for it and when then having the proper parameters to control these you can calculate your MCU need and how it has to operate.
You can start…
Hi Tashfique,
In addition to Wilson's comments, you can also examine the gerbers of the DRV8839EVM. These can be found by searching for the DRV8839EVM and moving down to the software section. The most current zipped file contains the schematics, gerbers…
Part Number: DRV8839 Hi all,
We are using a DRV8839 to drive 2 micro solenoids of 3.3V in a custom board. We have tested the 6 boards (prototypes) and we see the same problem: the thing is that when we set the INx and ENx pins to '1' (3.3V) the corresponding…

Although I still need to use power line to transmit the data about the motor's speed or something else to control the motor.
So, do I need to buy a new device or any software I can use?
if you wish implement motor control…
