Part Number: DRV8899-Q1 Tool/software: Hello,
My customer will use a stepping motor to work at 9.5V constant voltage. It has coil with 60ohm, so it needs around 158mA. If I look at the datasheet of DRV8899-Q1, it can control the output current by TRQ_DAC…
Part Number: DRV8899-Q1 Dear Team,
We are currently investigating unexpected behavior related to the Overcurrent Protection(OCP) mechanism in the DRV8899 device.
During our testing, while the stepper motor was operating normally, we intentionally…
Hello Basavaraju,
Thank you for your question.
Basavaraju Patel said: What are the minimum and maximum delay values that can be configured between step pulses?
It is mentioned in 6.7 Indexer timing requirement. The step pulse is a pulse with 50…
Part Number: DRV8899-Q1 Tool/software: Hello Team,
Kindly update us could we left open the below unused pins. do required any strong pull down resistors on the pins?
STEP and DIR pins
revert back to us ASAP

Part Number: DRV8899-Q1 Hello Team,
I have a concern regarding the handling of the TRQ_DAC register bits in the CTRL1 register. As per my understanding, the supported bit values range from 0 to 15.
Initially, I set the bit value to 7. However, in…
