LP8866QDCPRQ1 TI Automotive LED Driver | 38-HTSSOP | 4.5V-40V, 6 Channels

Product Overview

The LP8866QDCPRQ1 is a high-performance automotive-grade LED driver from Texas Instruments, designed for advanced lighting systems. It integrates six constant-current channels with adaptive boost control, supporting up to 150 mA per channel. Housed in a 38-HTSSOP package, it operates over a wide input voltage range of 4.5V to 40V, making it suitable for 12V and 24V automotive systems. The device features PWM dimming with a 5000:1 ratio, spread spectrum for EMI reduction, and comprehensive fault protection including LED open/short detection and thermal shutdown.
