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.
