Annie,
There is no way to adjust the slew rate (output rise/fall time) on the DRV8874 itself.
However, we do have an automotive variant with edges approximately 3x slower.

Part Number: DRV8874-Q1 Hi Team,
I received the following request on DRV8874-Q1:
###.
If I understand correctly, beyond the heat dissipation the device can pull for a limited period 6A!
I see that the gain error is defined only up to IOUT <4A.
Does…

But we need the specification how much…
Hello,
Can you clarify what "EMS" stands for? Electromagnetic ___?
Here is its DRV8874-Q1 Functional Safety FIT Rate, FMD and Pin FMA report.

Part Number: DRV8262 Other Parts Discussed in Thread: DRV8243-Q1 , DRV8874 , DRV8962 Hello,
I have a project where we need to drive a 24V, 5A thermoelectric cooler. Need H-bridge because we need to switch polarity based on whether we are heating or cooling…
The customer refers to the similar problem about current inaccuracy in this thread, but the problem is not solved.

Part Number: DRV8243-Q1 Other Parts Discussed in Thread: DRV8874 , DRV8874-Q1 Hi Experts,
May I ask if can you please give the information about the accuracy of the current measurement of the two components: DRV8874 and DRV8243-Q1?
Thank you and best regards…
Hi Sherry,
Thank you for your questions.
1. DRV8243-Q1 has good accuracy in higher current 0.8A-4.3A, but not in lower current range as trade off. If customer need +/-10% accuracy in 0.6A, DRV8876-Q1 is our recommendation. DRV8876 has less current capability…
Part Number: DRV8904-Q1 Other Parts Discussed in Thread: DRV8874-Q1 , DRV8876-Q1 , DRV8876 Hello,
My customer is interested in DRV8904-Q1, but they'd like to have >2kHz from the PWM generator. If I understand correctly, DRV89xx-Q1 devices can output…
Hello Pedro
Thank you, My client select DRV8874-Q1, Now the question is that only one model is found in the data manual of H-bridge driver drv8874-q1. Are different DSPs corresponding to different models or compatible? Because the DSP we use is 3.3V, do…
