Hi Fabio,
The DRV8813 was not intended to operate in this manner.
The DRV8814 is the preferred device. When the DECAY pin is set to 0, the logic table allows LL.
The DRV8841 and DRV8842 are also better choices for this type of operation. The…
Hi Renan,
There is the DRV8843-EP which is an enhanced package version of the DRV8842. It can support defense, aerospace, and medical applications. It also supports military temperature range (-55C to 125C). Unfortunately, this device is out of stock…
Hi Chris,
Instead of the DRV8841, please take a look at the DRV8843. The truth table matches the DRV8833 with the voltage and current specs of the DRV8841.
For the 5A, two DRV8701s with external FETs may work. It is missing the x1/x0 inputs of the…
Hi James,
Thanks again for your input.
One last question, so the DRV8841 , DRV8843 , and DRV8844 chips the motor speed is controlled by PWM. I have also seen the DRV8830 chip in the search, is this controlled by I2C commands?
Thanks,
Rocketma…
Hi Javier,
Are you planning to use the DRV8711 to drive the DRV8843? The DRV8711 is designed to drive external FETs, while the DRV8843 contains integrated FETs. The output of the DRV8711 would damage the input to the DRV8843 in the configuration described…
Hello Wilson,
I think that it would be best to drive my application using the DRV8843 from a cost perspective. I actually want the DRV8841 since I have no use for external PWM but it seems that it is not available on Farnell.
Anyways, is it possible…
Hi Milos
You come to the right place. All DRV88xx drivces will give you good short protection no matter you short the output to GND, VM or cross each other.
DRV8841 , DRV8843 or DRV8844 will be a matching one. You can check those datasheet in detail…
Other Parts Discussed in Thread: DRV8843 is there any PCB model for DRV8843 or any equivalent symbols that has same size and pin space so I can design a pcb for the driver?
Hi, Jose
Thank you for your time.
I am still curious that why not connect VMA and VMB internally and just derive ONE pin VM outside?
And for DRV8843 which can drive tow DC motor, it also said that VMA and VMB should connected to the same supply…
