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, the…
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-pinch…
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…

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 adjusting…
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, IN2=0,…
Mark Philip Felipe said: Switching at 20-40Khz and use an 8 bit value to determine the duty cycle. Since this is closed loop servo application, the output may theoretically change back and forth (CW or CCW) every 1 ms (or 1000 uS). In reality, the mechanical…

Hi,
We've selected the DRV8871 chip to drive the 12V 4W latching solenoid: DSML-0630-12C.
However, we noticed in this topic here on TI forum that the DRV8871 is listed as not supporting…
Part Number: DRV8871 hi all,
i use in my design DRV8871 and sample an overshoots on the IN1 and IN2 pins in the moment that i connect the supply (all other pins are unconnected).
how it is possible? some has an idea?
BR,
Itzi
Thank you very much Ryan. In my case, I am using Adafruit DRV8871 (which uses the TI driver DRV8871). I think that pin "PGND" and "GND" are already internally connected in the breakout board, as per this schematic (available here )…
