LP8868XQDMTRQ1 TI LED Driver | 14-VSON (4.5x3) | 4-Ch, 150mA, AEC-Q100

Product Overview

The LP8868XQDMTRQ1 is a high-performance, automotive-grade LED driver from Texas Instruments, designed for precision current regulation in advanced lighting systems. Housed in a compact 14-VSON (4.5x3) package, this device integrates four independent current sinks capable of delivering up to 150 mA per channel. With AEC-Q100 qualification, it ensures reliability in harsh automotive environments. The LP8868XQDMTRQ1 features flexible dimming control via PWM or analog methods, making it ideal for dynamic lighting applications such as adaptive headlamps, daytime running lights, and interior ambient lighting. Its low dropout voltage and high efficiency minimize power dissipation, while built-in fault protection (open/short LED detection, thermal shutdown) enhances system safety.
