Part Number: DRV8884 Other Parts Discussed in Thread: DRV8886 Dear Sir,
I have fixed mode of operation of IOs of DRV8884 like TRQ, M1/M0, DECAY.
Details are as below.
1) TRQ, M1 - need to be logic low.
2) M0 - need to be logic high.
3) DECAY…
Part Number: DRV8884 Other Parts Discussed in Thread: DRV8886 , Hi team,
When using the current setting by connecting a resistor between the RREF pin and GND, does the IFS accuracy change from ±6.25% when the IFS setting (resistor value) is changed…
Part Number: DRV8884 I need to control the drive current to my motor in finer steps than can be achieved with just the TRQ control. Not having a PWM signal available, I instead implemented a simple 4 bit DAC by using open collector outputs drive a series…
Part Number: DRV8884 Hi,
I am using 12V / 300mA unipolar stepper motor which is driven by DRV8884 driver IC with 12v supply.
Settings of driver IC is as below:
1) M1 = 0, M0 = 1, 1/16 micro stepping
2) TRQ = 0, current scaler to 100%, (no current…
Part Number: DRV8884EVM Hi
I have a problem with the DRV8884EVM 。when I turn on the power （power of mcu and motor driver），mcu is good running; and then I just set nSleep pin to high, nFault pin changes to low, and keeps low until set nSleep pin to low…

Part Number: DRV8884EVM Other Parts Discussed in Thread: DRV8884 , DRV8885 , DRV8886 Hello team,
I got the question from the customer about the DRV8884/5/6 thermal measurement result on EVM.
They measured all that device with the same condition…
Part Number: DRV8884 Hi, Motor Driver support team
Which side FETs is turned on when Soft Decay mode is enabled? My understanding is that the low-side FETs is usually used in soft decay mode. I would like to know if high-side FETs may be turned on instead…
Part Number: DRV8884 Hello team!
I would like to know there's any limitation for external components for controlling RREF with PWM resource.
Especially, C1 value in the picture below.
From my understanding, those values are flexible unless not affect…
