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 7…
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 datasheet…
Just to update you. We realize the DC motor is just too demanding for the DRV8850. There is no driver IC available that we could find, that can handle such high current at low voltage. We had to build a custom driver for this product. Even a high current…
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 able…
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)
I can…
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 Other Parts Discussed in Thread: DRV8873 We are using DRV8850 motor driver in our project. We are measuring current flowing through the motor, using VPROPI output. Schematics attached below. VMTR is 5.5V. The motor is connected to…
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 motor…
