Part Number: DRV8871 Tool/software: HI
We are using the DRV8871 to drive an actuator.
actuator Voltage : 24V
actuator Operation Current : 0.05A
Upon checking with an oscilloscope, an inrush current of 8.6A was observed.
In the following situation…
Part Number: DRV8871 Tool/software: Hi ti team,
1. We originally expected to rely on the overcurrent stall protection function of the IC to avoid the risk of finger pinch in our product (due to product design issues, it is necessary to achieve anti…

Hello, I'm encountering an issue with the DRV8871 motor driver and would appreciate some insight. I've been testing it with a DC motor and experimenting with the current limitation by…
Part Number: DRV8871 Tool/software: Hello,
I am running into an issue when I try to run a motor without having it pulse, but as I increase the voltage it starts pulsing around 12-13V. I am using the Adafruit DRV8871 Brushed DC Motor Driver Breakout…
Part Number: DRV8871 Tool/software: I have a doubt in using bulk capacitance.
I have used 47 uF tantalum capacitor (bulk capacitance) in the Vm pin
But the size is little big. I can't use it.
Can I use ceramic capacitor in that pin with the same…
Part Number: DRV8871 Tool/software: I'm experiencing a derating issue with the RLIM resistor in DRV8871DDAR. The calculated derating value is too high, resulting in resistor failure.
Details,
ILIM = 1.5 A
RLIM = 47K ohms (As per the RLIM calculation…
Part Number: DRV8871 Tool/software: Please confirm and provide the actual dimension of the exposed thermal pad, since there are two actual dimensions are available in the latest datasheet.
Part Number: DRV8871 In rare cases, the waveform shown in the attached image was obtained as a result of applying the brake while the DC motor was rotating forward. What can you think?
See schematics, waveforms, and enlarged waveforms.

Part Number: DRV8871 Tool/software: Hi, I'm looking for a pwm motor speed driver. I like to use up to 3 motors rated about 650ma each power with 10v. If operating in constant current will draw about 2amps. Also, the start up current will be higher, but…
Part Number: DRV8871 Other Parts Discussed in Thread: DRV8870 , DRV8873 , DRV8243-Q1 Hi Team,
Q1:
The input terminals IN1 and IN2 of DRV8871 input static data. For example, IN1=1 (high level), IN2=0 (low level), the duration is 200ms, then IN1=0,…
