Overview
The A6260KLJ-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 package with exposed pad (SOIC-Narrow-8) and is qualified to AEC-Q100 standards. The operational temperature range spans from -40°C to +125°C.
Feature Summary
- Supports PWM dimming for brightness adjustment via ENABLE input
- Includes integrated battery reverse polarity protection
- Features thermal shutdown circuitry to prevent overheating damage
Applications
- Automotive interior lighting such as reading lamps
- Automotive exterior lighting including turn signals and brake lights
- Trunk and cargo area illumination systems
Procurement Notes
Verify the suffix 'T' indicates tape-and-reel packaging configuration. Confirm AEC-Q100 qualification status matches specific project requirements. Check moisture sensitivity level (MSL 3) handling constraints during assembly. Ensure compatibility with SOIC-Narrow-8 footprint on PCB layout.
Selection Notes
Select this component for high-brightness LED applications requiring precise current regulation. Consider its linear topology for simpler design compared to switching regulators. Evaluate thermal performance given the exposed pad package for heat dissipation needs. Verify input voltage stability against automotive load dump conditions.
Part Context
Part of the A6260 series, this driver complements Allegro's portfolio of constant current LED solutions. It targets markets demanding robust automotive-grade components with integrated protection features. The family includes variants with different packages and current ratings to suit diverse application constraints.
Replacement Considerations
A6260SLJTR-T is a discontinued variant within the same series offering similar functionality but with a narrower operating temperature range (-20°C to 85°C). Direct replacement requires verification of thermal management capabilities under extended temperature conditions.
