Part Number: DRV8850 Tool/software: Hi All,
I have a question about the DRV8850.
If I'm not using the VPROPI pin, is it okay to leave it open?
Best Regards, Ishiwata
Part Number: DRV8850 Other Parts Discussed in Thread: DRV8411A Colleagues,
I’m considering DRV8850 for a new design which will be powered with 4x alkaline cells in series. It would be convenient if I could run the DRV8850 from 6.0V . The Abs max is…
Part Number: DRV8850 Other Parts Discussed in Thread: DRV8870 , Hi Ti experts,
Why does DRV8850 have 4x input pin to control H bridge. Correspondingly, the DRV8870 has only 2x input.
What are the application scenarios of the four inputs.
In DRV8850…
Part Number: DRV8850 Having a problem with DRV8850. Often it will not deliver adequate power to the motor. If we remove power from the chip and try again, it works. Not sure if we are missing something.
Its a fairly high current application, but within…
Part Number: DRV8850 We are developing a new motor design with the DRV8850. Its a great chip, but we've had some unexplained failures. For no apparent reason, the driver will stop functioning. It then goes into a high current draw at idle. From 0.3 -…
Part Number: DRV8850 We are trying to smooth out our motor voltage as much as possible. Its a small battery powered system, so the PWM is mirrored in the battery voltage drop. This can cause problems. So our goal is to increase the PWM frequency and increase…
Part Number: DRV8850 Hi,
I'm using a DRV8850 to drive a very small DC motor on 3.7V battery,
The Vpropi pin is connected to a 4.3kOhm resistor and voltage is measured by the MCU's ADC.
On empty load the motor use about 15mA.
Some boards are…
Part Number: DRV8850 I am trying to sample VPROPI pin on DRV8850 Evaluation board but there is a lot of noise on the pin along with the signal.
How do I remove that noise? I will be using ADC to sample the VPROPI pin.
I am using CC3220 to drive the…
Part Number: DRV8850
Hi Team,
My customer use DRV8850, below is the SCH,
VadjG = 3V TEC-EN-G = 5V TEC-IN1-G=5V TEC-IN2-G = 0.9V But there's no output in OUT2-G & OUT1-G, voltage are both about 0.02V.
What might be the problem?
Part Number: DRV8850 I want to reduce LDO current as low as possible for my application.
I found the biggest power consumption from resistor divider.
for example :R1=4.7K, R2=2K, Vout=2.68 then we have at leat 400uA(2.68V/6.7K) + 40uA(LDO enabled…
