Texas Instruments ULC1001/ULC1001-Q1 Configurable PWM Modulator

Texas Instruments ULC1001/ULC1001-Q1 Configurable PWM Modulator has specific current and voltage sensing capabilities for piezo-based lens cleaning systems. An on-chip, low-latency DSP supports Texas Instruments’ proprietary algorithms designed for lens cleaning. The ULC1001/ULC1001-Q1 and DRV2911-Q1 work together to create an Ultrasonic Lens Cleaning system. The ULC1001/ULC1001-Q1 device is available in a 32-pin QFN-HR package for a compact PCB footprint. The Texas Instruments ULC1001-Q1 devices are AEC-Q100 qualified for automotive applications.
