Dear Ivan,
We could get the DRV2665 to work on a custom PCB. It doesnt work at all on a breadboard. Although it is interesting to see how the IC resets on the oscilloscope. Can you keep the thread open so that I can post a pic of the IC resetting? I…
Part Number: DRV2665 Other Parts Discussed in Thread: DRV2667 Is it possible to use the DRV2665/DRV2667 with an external boost regulator instead of using the internal one?
Part Number: DRV2665 Other Parts Discussed in Thread: DRV2700 Dear Sir/Madam,
In DRV2665 datasheet: It mentioned:
8.2.2.2 Piezo Actuator Selection
There are several key specifications to consider when choosing a piezo actuator for haptics, such as dimensions…
Other Parts Discussed in Thread: DRV2665 , DRV2667 Hello, I am trying to control a DRV2665 using an Arduino Due board. I have implemented the application circuit listed in the datasheet on page 20 with the suggested components (chip is mounted to a small…
Other Parts Discussed in Thread: DRV2665 , DRV2667 , DRV8662 Hello Expert
My name is Noriaki Fukazawa.
I have a question about DRV2665 and DRV2667 .
I understand these product can be use to drive the piezo electric element.
What is driving the smallest piezo…
Hi Jeff McPherson,
Thank you for your reply.
>Can you rephrase or elaborate?
⇒Is there a relationship (restriction) between VDD power supply voltage and VIN?
I checked the simulation waveform using a similar DRV2665 and think the viewpoint of…
Part Number: DRV2665 Other Parts Discussed in Thread: DRV8662 From the datasheet it is not clear if the output is an AC waveform only. I need the hold the actuator in potions not cycle quickly back and forth. Will this IC support this need?
I need full…
Other Parts Discussed in Thread: DRV2665 , DRV2667 Hi all Would you mind if we ask DRV2667 and DRV2665? We can't find the max output current about these devices. So, could let us know these? Kind regards, Hirotaka Matsumoto
Part Number: DRV2700EVM Other Parts Discussed in Thread: DRV2700 , DRV2665 Looks like the DRV2700 does not drive piezo above 20khz. Does TI have any alternate driver chips that can drive a piezo at around 30khz with 100-200V?
