Overview
The A6260KLJTR-T is a linear LED driver IC from Allegro MicroSystems, designed for automotive and industrial applications. It features a single output channel capable of delivering up to 350 mA with PWM dimming control. The device operates within an input voltage range of 6 V to 40 V and supports adjustable output voltage. It is housed in an 8-SOIC-EP package and is qualified to AEC-Q100 standards. The component functions effectively across a temperature range of -40°C to +125°C.
Feature Summary
- Integrated battery reverse protection minimizes the need for external diodes.
- Built-in thermal shutdown circuit disables the IC if junction temperature reaches approximately 165°C.
- Temperature monitoring circuit enables foldback current reduction to protect LEDs during high-temperature conditions.
- Controlled output current slew rate reduces electromagnetic interference (EMI) during switching.
Applications
- Automotive interior lighting such as reading lamps and dome lights
- Automotive exterior lighting including turn signals and brake lights
- Trunk illumination systems
- Industrial high-brightness LED lighting
- Consumer high-brightness LED applications
Procurement Notes
Verify the specific suffix KLJTR-T against official datasheets to confirm package type and tape-and-reel specifications. Ensure compatibility with AEC-Q100 automotive grade requirements for your target application. Cross-reference manufacturer part numbers with distributor listings to avoid confusion with similar variants like A6260SLJTR-T which may have different temperature ranges.
Selection Notes
Select this component for designs requiring a single-channel constant current solution with integrated protection features. The linear topology suits applications where efficiency is secondary to simplicity and low noise. Consider the 8-SOIC-EP package for thermal management needs. Verify that the 6 V to 40 V input range aligns with the system power supply architecture.
Part Context
This part belongs to the A6260 series of LED drivers from Allegro MicroSystems. It is specifically engineered for robust performance in harsh environments, featuring comprehensive protection mechanisms. The series targets the automotive market while remaining suitable for general-purpose high-brightness LED applications in industrial and consumer sectors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternatives based on pin compatibility, electrical specifications, and package dimensions only after verifying official manufacturer substitution lists.
