ICs ideal for Headlamps & Rear Lamps

for automotive Headlamps & Rear Lamps

Headlamps continue to evolve from halogen lamps to HID and LED. In addition to their basic performance which improves visibility at night and in bad weather, headlamps also play an important role in ADAS. Examples of ADAS include, an Auto Leveling System that adjusts the optical axis vertically according to the vehicle's front/rear tilt, an AFS (Adaptive Front Lighting System) that automatically moves the optical axis left or right according to the steering wheel angle and the vehicle speed, and an ADB (Adaptive Driving Beam) that uses cameras to control the high beam by recognizing oncoming vehicles and vehicles driving in front. Rear Lamps are also being switched from bulbs to LEDs which are more advantageous.
ABLIC offers ICs ideal for Headlamps and Rear Lamps, which continue to evolve. ABLIC offers a comprehensive range of products: such as LDOs with built-in watchdog timers for monitoring MCUs, battery monitoring ICs that monitor 12V auxiliary batteries for abnormal voltages, Zero Crossing Latch Hall effect ICs which operate ideally in BLDC motors for auto-leveling and cooling fans.
