Diodes Incorporated Unveils 40V Buck LED Driver for Automotive Use
Diodes Incorporated Unveils the AL8841Q: A Reliable and Cost-Effective Automotive LED Driver
BonChip Electronics, a trusted distributor of Diodes Incorporated's industry-leading power management solutions, is excited to announce the availability of the new AL8841Q automotive buck LED driver. This innovative product empowers automotive designers to create efficient and robust LED lighting solutions for various applications.
A Versatile Solution for Automotive LED Lighting
The AL8841Q is a cost-effective and reliable buck LED driver specifically designed for the demands of automotive LED lighting:
- Efficient Driving of Series-Connected LEDs: The driver allows for efficient control of single or multiple series-connected LEDs, drawing power from a higher voltage source.
- Wide Input Voltage Range: The device operates seamlessly within a wide input voltage range of 4.5V to 40V, ensuring compatibility with various automotive electrical systems, including the entire 12V battery range.
Adjustable Output Current and Simple Design
The AL8841Q offers exceptional flexibility and ease of use:
- Externally Adjustable Output Current: Delivering an output current of up to 1A for the TSOT25 package and 1.5A for the MSOP-8EP package, the driver allows for precise LED current control using an external resistor.
- Integrated Power Switch and Minimal External Components: By integrating the power switch, the AL8841Q simplifies design and minimizes the external component count to just four, contributing to a compact footprint.
Comprehensive Control and Protection Features
The AL8841Q provides advanced control functionalities and robust protection mechanisms:
- Versatile Dimming Options: The CTRL pin empowers users to adjust LED brightness through either a DC analog voltage signal or a PWM digital signal, offering flexibility for dimming control.
- Soft-Start Time Adjustment: The CTRL pin also facilitates adjustment of the soft-start time through an external capacitor, enabling control over LED power-up behavior.
- Fast PWM Dimming Response: A low voltage (0.3V or lower) applied to the CTRL pin disables switching but avoids low-power standby, resulting in a faster response to PWM dimming compared to Diodes' AL8860Q/61Q drivers.
Thermally Enhanced Package Options
The AL8841Q is available in two package options, catering to diverse design needs:
- Thermally Enhanced MSOP-8EP: This package prioritizes efficient thermal management, ideal for applications requiring high power dissipation.
- Small-Footprint TSOT25: For space-constrained designs, the TSOT25 package offers a compact solution.
Key Applications for the AL8841Q
The AL8841Q's versatility makes it suitable for a wide range of automotive LED lighting applications:
- Daytime Running Lights (DRLs)
- Fog Lights
- Turn Signals and Brake Lights
- Dimmable Interior Lighting
- Puddle Lamps
Qualified for Automotive Applications
Meeting stringent automotive standards, the AL8841Q is an excellent choice for automotive LED lamp designs:
- AEC-Q100 Qualification: The device is AEC-Q100 qualified, ensuring adherence to rigorous automotive electronics reliability standards.
- IATF 16949 Certified Manufacturing: Manufactured in IATF 16949 certified facilities, the AL8841Q guarantees consistent quality and production processes.
- PPAP Documentation Support: Diodes Incorporated provides PPAP documentation to streamline the automotive design approval process.
