Part Number: DRV8662 Other Parts Discussed in Thread: TINA-TI , DRV2700 Hello!
I am trying to simulate the DRV8662 in MATLAB Simscape. The first step of this process requires converting its TINA-TI model to a generic SPICE model, as described in this …
Part Number: DRV8662 Hi Team,
Customer would like to know where is the output control external device interface on the chip DRV8662?
Best regards,

Hi team,
Here's an issue from the customer may need your help:
How to get this chip to output a sine wave of 150vpp? The customer can get the correct waveform, but the voltage is always…
Part Number: DRV8662 Other Parts Discussed in Thread: DRV2700 I was looking at using DRV8662 or similar chip for this application, but the chip appears to be for audio applications up to 20 KHz, whereas the piezo motor operates at 28KHz. Is there a suitable…
Part Number: DRV8662 Hi Team,
Good day. I am posting this inquiry on behalf of the customer.
"We are doing research in Fluid mechanics at Queen Mary University
We have designed a device that uses a speaker as an actuator.
To drive the speaker…
Hi Ryu,
Understood. Unfortunately we don't have that kind of data. We only have a VDD sweep. Data over time is redundant, the failure is instantaneous. There is almost certainly some kind of trend with temperature but we don't have the data to know in…
Part Number: DRV8662 I am designing a driver circuit for a piezo motor. But i haven't found much documentation on the design (maybe cause of piezo motor is new technology and haven't been used much) As I know based on the manufacturer's documents…
Part Number: DRV8662 Hi team,
DRV8662‘s output is normal on condition of no p iezo load, but output abnormal with piezo load
Attached are the waveform with and no piezo load!
SCH is same to the DRV8662EVM schematic
piezo load is 3.7uF
Gain1=Gain2=0 …
