3 Description

The ULC1001-Q1 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-Q1 and DRV2911-Q1 work

together to create an Ultrasonic Lens Cleaning

system.

The ULC1001-Q1 device is available in a 32-pin QFNHR

package for a compact PCB footprint.
