A6261KLPTR-T

Overview

The A6261KLPTR-T is a four-channel linear LED driver IC designed for automotive applications. It operates within a supply voltage range of 6 V to 50 V and delivers an output current of 100 mA per channel. The device utilizes a buck topology with adjustable output voltage and supports PWM dimming. It is housed in a 16-eTSSOP-EP package with exposed pad, rated for operation between -40°C and +125°C.

Feature Summary

Four independent linear output channels for precise LED current control
Integrated internal switching capability supporting buck topology
Supports pulse-width modulation (PWM) dimming functions
Automotive-grade qualification compliant with AEC-Q100 standards

Applications

Automotive exterior lighting systems
Interior vehicle illumination circuits
LED matrix driving applications
General automotive LED backlighting

Procurement Notes

Verify the specific suffix KLPTR-T against official Allegro MicroSystems documentation to confirm pinout and thermal pad configuration. Ensure compatibility with existing PCB footprints for the 16-eTSSOP-EP package. Confirm that the design accounts for the maximum operating temperature of +125°C and the 50 V input limit during procurement validation.

Selection Notes

Select this component when a four-channel solution with integrated linear regulation is required for automotive environments. The 100 mA per channel rating suits standard indicator and ambient lighting loads. Consider the 16-pin TSSOP package for space-constrained designs requiring exposed pad thermal management. Verify that the system input voltage remains within the specified 6 V to 50 V window.

Part Context

This part belongs to the A6261 family of automotive LED drivers from Allegro MicroSystems. The family offers various channel counts and packages to address different lighting architectures. The KLPTR-T designation specifically identifies the 16-pin TSSOP variant with tape-and-reel packaging, distinguishing it from other package options like MSOP or SOIC within the same functional series.
