Part Number: DRV8220EVM Other Parts Discussed in Thread: DRV8220 Tool/software: I'm just looking for a simple and fast way to drive some piezos using an H-Bridge strictly for the purposes of testing. Is there any reason this EVM can't be used for this…
Part Number: DRV8220EVM Other Parts Discussed in Thread: DRV8220 , Dear Team:
If the customer increases the operating frequency, the current will become a triangle wave as shown in the figure below
Is this normal? What is the reason?

Part Number: DRV8210EVM Other Parts Discussed in Thread: DRV8212EVM , DRV8220EVM , Version A and E1 of the DRV8210EVM, DRV8212EVM, and DRV8220EVM have a silkscreen error where the "IN1/EN" and the "IN2/PH" silkscreen label placement is incorrect. The…
Hello,
Typically for latching solenoids t he sequence begins with both IN1 and IN2 set to LOW (0V), which is the initial state. To switch the solenoid to the "ON" position, IN1 is set to HIGH (VCC) and IN2 is set to LOW (0V) for a short duration, typically…
Hello,
So for 12V / 6W that's 0.5A current.
While you could use DRV103, I suggest using a newer part like DRV8220 . This is a 20V max, up to 1.76A device. You can order an EVM to quickly evaluate it: DRV8220EVM Evaluation board | TI.com . You can…
Hey Dharmesh,
Those voltages don't seem right when powered at 12V/GND, OUT1 should be 12V and OUT2 should be 0V or very close. Can you try repeat the test without a load, and with a resistor as the load?
Also consider ordering an EVM to test it on…
Hey Jaakko,
Thank you for your question.
Please find my schematic review in the attached PDF. Usually damage like this occurs due to some sort of Abs max violation. I suggest looking into the bulk capacitances on VM as suggested in the pdf.
