GALT62120

Geehy's GALT62120 automotive high-side LED driver supports 12 channels of precise high-side current output for pixel-level LED control. It integrates programmable 12-bit PWM dimming with linear and exponential modes, and features LED open/short detection, over-temperature protection, and other safety mechanisms. Designed to meet AEC-Q100 Grade 1 standards, it supports full-width/graphical tail lamps, headlamps, dynamic turn signals, welcome lights, turn signals, cluster indicators, and interior ambient lighting.
