Diodes Incorporated Reveals Triple-Channel LED Driver IC Tailored for Vehicle Lighting Systems
Diodes Incorporated Unveils Advanced Three-Channel Linear LED Driver for Enhanced Automotive Lighting Control
Diodes Incorporated (DIOD), a leading innovator in the discrete and analog semiconductor market, has introduced the AL1783Q, a groundbreaking automotive-compliant linear LED driver.
Advancements in automotive design focused on the user experience have led to an increased need for multi-channel LED drivers. These drivers empower passengers to customize their cabin lighting ambiance by altering the light colors as desired. Additionally, they contribute to enhanced safety by powering animated turn signals and adaptive grille illumination that respond to varying driving conditions. The AL1783Q driver features individually adjustable dimming controls for every channel and employs pulse width modulation (PWM) for precise LED dimming. With settings for LED current defined by an external REF pin, this driver is a versatile choice for a vast array of lighting solutions in both electric (EV) and internal combustion engine (ICE) vehicles.

Elevating Automotive Lighting with Independent Color and Brightness Control:
The AL1783Q caters to the growing trend of human-centric automotive design. This innovative driver empowers users to independently control the brightness and color of each of its three channels. This functionality allows for features like:
- Mood lighting: Vehicle occupants can easily adjust the interior lighting color to create a desired ambiance.
- Enhanced safety: Animated turning indicator signals and exterior grill lighting can be activated based on road conditions, improving visibility and alerting other drivers.
Designed for Demanding Automotive Applications:
The AL1783Q boasts several features that make it ideal for automotive environments:
- Independent dimming control: Each channel features independent dimming controls, enabling precise lighting adjustments.
- Pulse width modulation (PWM): The driver utilizes PWM for efficient LED dimming.
- Wide input voltage range: The AL1783Q operates from a 55 V rail, exceeding the capabilities of most LED drivers (limited to 40 V) and accommodating the automotive industry's shift towards higher voltage rails. This also allows for support of increasing LED chain voltages.
- High current output: Delivering up to 250 mA per channel (66% more than the standard 150 mA), the AL1783Q offers superior flexibility for powering a wider range of LED lighting applications.
- Adjustable current control: Individual resistors provide the ability to fine-tune the current in each channel.
- Robust thermal performance: Housed in a thermally efficient TSSOP-16EP package with an exposed cooling pad, the AL1783Q ensures excellent heat dissipation.
- Enhanced reliability: The driver incorporates multiple fault detection features, including undervoltage lockout (UVLO), overvoltage protection (OVP), and open/short circuit detection for LEDs, guaranteeing reliable system operation.
The AL1783Q paves the way for a new era of customizable and feature-rich automotive lighting. Contact BonChip Electronics today to learn more about this innovative driver and how it can revolutionize your automotive lighting designs!
