A6260SLJTR-T

Overview

The Allegro A6260SLJTR-T is a linear constant current LED driver designed for automotive and industrial applications. It operates within an input voltage range of 6 V to 40 V, supporting a typical adjustable output current up to 350 mA per channel. The device features a single output channel with PWM dimming capability via an ENABLE input. It is qualified to AEC-Q100 standards and functions across a temperature range of -20°C to 85°C. Packaged in an 8-SOIC-EP surface-mount format, it includes integrated protection against ground shorts, battery shorts, and over-temperature conditions.

Feature Summary

• Linear constant current regulation with PWM dimming control
• Integrated thermal shutdown and temperature monitoring circuitry
• Built-in reverse battery protection minimizing external component requirements
• Automotive-grade reliability with AEC-Q100 qualification

Applications

• Automotive interior lighting such as reading lamps and dome lights
• External vehicle lighting including tail turn signals and brake lights
• Trunk and cargo area illumination systems
• Industrial high-brightness LED lighting modules
• Consumer LED lighting applications requiring robust drive characteristics

Procurement Notes

Verify the specific suffix SLJTR-T confirms the -20°C to 85°C operating temperature range and automotive grade status. Confirm package type matches 8-SOIC-EP with exposed pad. Check manufacturer documentation for current production status as variants may be discontinued. Ensure compatibility with system voltage limits not exceeding 40 V. Validate pinout configuration against target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for single-channel LED driving where linear regulation suffices. Consider the 350 mA maximum output current limit for load sizing. Evaluate the 6 V to 40 V input window against supply rail variations. Assess thermal management needs given the linear topology and exposed pad package. Compare against higher voltage tolerant or multi-channel alternatives if system requirements exceed these specifications.

Part Context

This part belongs to Allegro's dedicated LED driver family targeting automotive illumination markets. It complements other models like the A6260KLJTR-T which offers extended temperature ranges. The series emphasizes integrated protection features and simple PWM control interfaces. It serves as a solution for replacing discrete transistor-based drivers with a compact, reliable IC option for standard automotive lighting architectures.

Replacement Considerations

A6260KLJTR-T offers identical electrical performance but supports an extended temperature range of -40°C to 125°C. Verify that the wider temperature specification meets the application environment requirements. Package dimensions and pinouts remain compatible between these variants. No functional changes are introduced by the suffix difference beyond environmental ratings.
