Overview
The A6261KLJTR-T is a linear LED driver IC from Allegro MicroSystems, designed for automotive applications. It features four independent output channels with an adjustable current capability of up to 200 mA per channel. The device operates within a supply voltage range of 6 V to 50 V and supports PWM dimming control. Packaged in an 8-SOIC-EP (SOIC-Narrow-8) surface-mount package with an exposed pad, it functions as a Buck topology driver. The component is rated for operation between -40°C and +125°C and holds AEC-Q100 qualification.
Feature Summary
- Four-channel linear LED driver architecture
- Automotive-grade AEC-Q100 qualification
- Integrated PWM dimming interface
- Exposed thermal pad for enhanced heat dissipation
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- Tail light assemblies
- Turn signal indicators
Procurement Notes
Verify the specific suffix 'KLJTR-T' against manufacturer documentation to confirm the 8-pin SOIC package and 200 mA channel rating. Ensure that the ordering quantity aligns with the standard reel packaging requirements specified by Allegro MicroSystems. Confirm RoHS compliance status and moisture sensitivity level prior to assembly processing.
Selection Notes
Select this component when a multi-channel solution is required for automotive LED arrays. The 200 mA per channel limit suits high-intensity applications. Consider the linear regulation type for noise-sensitive environments where switching frequency interference must be minimized. Verify that the PCB layout accommodates the exposed pad thermal requirements for optimal performance at maximum load.
Part Context
This part belongs to the A6261 series of multi-channel LED drivers. It shares functional similarities with other variants in the family but differs in package configuration and pin count. The KLJ suffix specifically denotes the 8-pin narrow SOIC footprint, distinguishing it from TSSOP or MSOP options available in the same product line.
