Part Number: DRV8886 Hello team!
I'd like to confirm my understanding is correct or not since I got the question from the customer.
1: Ifs can be set by resistor 15k ~ 300kohm, and Ifs value would be 0.015 to 2.0A based on fig11?
2: When it comes…

I design a PCB with modify the DRV8886 EVM with almost same schematics for DRV8886 driving area except adding one more step…
Part Number: DRV8886EVM Hello team,
I would like to confirm DRV8886EVM.
If we change the R1=15k to 12k, the EVM could have 2.5A?
I understand this device recommendation for Ifs is 2.0A, so the EVM RREF = 15kohm which the current will regulated in 2…
Part Number: DRV8886 Hi Team,
My customer is trying to control DRV8886's IFS dynamically by external DAC output. They want to know the settling time(The time from the time the DAC output is quarreled with to the time it is reflected in the IFS) though…
Part Number: DRV8886 Hello team!
I got the question from the customer below. Could you please support this?
In the customer system, IFS might exceed 2.0A. Is it okay to use this device with over 2.0A IFS if making sure temp is below 150℃?
My understanding…
Part Number: DRV8886 Hi Team,
My customer noticed that current rise time tend to be slightly shorter depending on load torque in DRV8886 evaluation. Do you know the reason why the current rise time was varied depending on load torque? I need to explain…
Part Number: DRV8886 Hello team!
I got 2 questions from the customer. Would you mind supporting those, please?
1: For regulation current accuracy, what's tolerant on TRQ value? Is this exactly 50 or 75 or 100%?
I'm assuming that the RREF & ARREF…

what is different between DRV8886 and DRV8886AT?DRV8886AT has the auto turn funtion, hardware side is P2P and how about the softwae?if I use DRV8886 before ,DRV8886 program code can…
Part Number: DRV8886 Hi Team,
My customer wants to minimize Ifs by controlling external DAC like indicated in "Controlling RREF With an MCU DAC" capture of datasheet. According to the datasheet, VRREF is estimated around 1.18 ~ 1.28V, so To set…
Part Number: DRV8886 Other Parts Discussed in Thread: DRV8884 Hi Team,
I want to know how large Rref we can select for current regulation in DRV8886. Possibly, I want to set 70mA Ifs but 432kohm Rref didn't wok on DRV8886 EVM, Ifs was 180mA min.
