Hey Maurtis,
Ahh okay understood, thank you for the detailed explanation!
First can you compare your circuit to this circuit in Open Load Detection in Integrated Drivers :
That application note has a lot of good info about getting OLD working
Maurits…
Part Number: DRV8873-Q1 In our design, there is only one DRV8873-Q1 chip used and I want to know how to test the SPI communication between MCU and DRV8873-Q1 is OK. What I mean is that when I send fixed data to DRV8873-Q1 and DRV8873-Q1 will definitely return…
Part Number: DRV8873 Hello,
My customer wants to leave the nFAULT pin floating.
It's mentioned in the datasheet that this pin SHOULD be pulled high to an external DVDD. Is this just a recommendation or a requirement?
Thanks,
Part Number: DRV8873 Hi Team,
1) Can the DRV8873 be applied to a 24-V system?
2) What is the maximum Load dump ( < 500ms) voltage that the chip VM can withstand?
3) Can the chip VM withstand 45 V? If so, are there any specific requirements?
4) Can chips…

Hello experts.
The current project wants to use the DRV8873-Q1 to drive a full-bridge brushed DC motor. The input voltage…
Part Number: DRV8873-Q1
We have 6 drivers on one board controlled by MCU. Each driver has individual nSLEEP signal, but all DISABLE pins connected together and switched to the ground via nFET. I would like to control all nOL pins in the same way, i…
Part Number: DRV8873-Q1 Hi Team,
There is only one 8873 in the customer's design being used. To confirm proper SPI communication between the 8873 and the MCU, the customer would like to test it with the following method:
While the MCU side sends any…
