Other Parts Discussed in Thread: DRV2911, ULC1001
Tool/software:
Dear TI experts,
My customer tests ULC1001-DRV2911EVM withe their own piezo module which they developed themselves.
THey connected this piezo module to EVM and tested it, bout they checked just little vibration, it was not the strength to clean water or dust.
The piezo's specification is as below.
- 1st Resonance frequency : 46.1KHz ± 2KHz
- Working voltage : 200Vpp
- Impedance : 123 ohm

Could you check the questions beolw?
1-1. Based on the specification, is my customer's piezo module suitable for ultrasonic lens cleaning system?
1-2. If not, what is the minimum specification of piezo module?
2-1. Does DRV2911 or ULC1001 have a function which can extend the resonance frequency or make frequency modulation of connected piezo module?
2-2. Or Can DRV2911 or ULC1001 control the piezo module only the range of frequency which piezo module have?
3. Do you have the specifications of piezo module of LCS-FL-RNG15?

Please check these issues. Thanks.
Best regards,
Chase
