  • DRV8871: Bulk capacitance

    TI Thinks Resolved
    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…

  • DRV8871: DRV8871 OCP

    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…

  • DRV8871: DRV8871-Technical problem

    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…

  • DRV8871: Derating issue in RLIM resistor

    Resolved
    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…

  • DRV8871: QUERY REGARDING ACTUAL DIMENSION OF THE EXPOSED THERMAL PAD

    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.

  • DRV8871: DRV8871

    Part Number: DRV8871 Other Parts Discussed in Thread: , DRV8251A 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…

  • DRV8871: Motor Speed Controller

    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…

  • RE: DRV8871: DC Moter ERROR

    Resolved
    It was stopped in coast mode. We discovered that there was a bug in the software control and were able to resolve it successfully.

  • DRV8871: Drive electromagnet

    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,…

  • RE: DRV8871: PWM and bidirectional control of DC motor

    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…
