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…

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…
Hi Wang Li,
Thank you for your inputs this is much appreciated, the post is for DRV8825 . I overlooked that DRV8850 is also tagged and it is my mistake.

Part Number: DRV8850 Hello,
I'd like to use half-bridges in the DRV8850 in parallel (OUT1 and OUT2 connected together), and connect the motor between this combined output and ground. I expect that I can drive the motor with more current that way. …
Part Number: DRV8850 Dear TI experts~
There are 2 problems about DRV8850
1. When we tested in the lab, the chip performed normally; after the prototype was handed over to the customer, there was no output of the chip, and it returned to normal after replacing…
Part Number: DRV8850 Hi,
I want to use DRV8850 for my current project.
Under datasheet Section 8.2.3 a typical delay between logical enable nSLEEP and motor current of 250us is specified.
Please let me know the maximum value.
Regards
Part Number: DRV8850 Hello there. We recently designed in the DRV8850 and screwed up the pinout because of an error in your datasheet. Figure 5 has the OUT2 and VCC pins reversed. I see this was reported on the forums back in February and you have not…
