3 Description
The ULC1001 is a configurable PWM modulator with
current and voltage sensing capabilities specifically
for piezo based lens cleaning systems.
An on-chip, low-latency DSP supports Texas
Instruments’ proprietary algorithms designed for lens
cleaning. The ULC1001 and DRV29xx work together
to create an Ultrasonic Lens Cleaning system.
The ULC1001 device is available in a 32-pin QFN-HR
package for a compact PCB footprint.
