ULC1001-Q1数据手册TI中文资料规格书

描述 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 QFN-HR package for a compact PCB footprint.
