Part Number: DRV8889-Q1 Hi,
Currently using DRV8889 and need to verify the SPI timing design function. It is necessary to ensure that t(READY), t(HI_nSCS), tdis(nSCS) are within the specifications. Do you have any suggestion how to conduct this test?
Thanks…
Part Number: DRV8889-Q1 Hi team,
Customer need DRV8889-Q1 OL detection function.
They think that the DRVOFF pin and DIS_OUT bit get same function based on following description in datasheet.
They did following 4 tests, and result as below:

Part Number: DRV8889-Q1 Hello DRV8xx team,
I got a question from customer(Hitachi/Astemo :OEM is TOYOTA)
When OCP is active and turn off FET, does DRV8889 detect "Open Load"? Based on the datasheet DRV8889 detects OL when IOL continue more than…
Part Number: DRV8889-Q1 Hello expert,
I find the Ifs formula in datasheet 7.3.5 current regulation, and how to calculate the current accuracy?
For the TRQ_DAC accuracy, should we refer to the accuracy below?
And the device just regulate the peak…
