A6274KLPTR-T-1

Overview

The A6274KLPTR-T-1 is a six-channel linear LED driver IC designed for automotive applications. It features integrated sine and cosine outputs from a 3D Hall-effect sensor, enabling precise current regulation based on external magnetic field positioning. The device supports PWM dimming with a maximum output current of 60mA per channel. It operates within a supply voltage range of 5V to 42V and is qualified to AEC-Q100 standards. The component is housed in a 20-TSSOP package with an exposed pad.

Feature Summary

• Integrates a 3D Hall-effect sensor with sine/cosine outputs for position-based control
• Provides independent linear current regulation across six output channels
• Supports high-resolution PWM dimming for precise brightness adjustment
• Includes comprehensive protection mechanisms against thermal and electrical faults

Applications

• Automotive interior ambient lighting systems
• Dashboard illumination arrays
• Door handle and console accent lighting
• General automotive low-current LED indicator circuits

Procurement Notes

Verify the specific suffix '-1' during procurement, as it denotes a tape change packaging update compared to the standard variant. Confirm that the required quantity aligns with the manufacturer's standard reel size of 12,000 units. Ensure the design accommodates the 20-TSSOP-EP footprint and thermal requirements specified in the official datasheet.

Selection Notes

Select this component when a single IC must drive multiple LEDs while simultaneously utilizing magnetic positioning data. It is suitable for designs requiring linear regulation rather than switching topology. Consider the 42V maximum supply limit and 60mA per-channel current capability when sizing the external circuit components.

Part Context

This part belongs to the A6274 series of multi-channel LED drivers from Allegro MicroSystems. It shares functional similarities with the A6284 but differs in channel count and specific sensor integration. The product line targets automotive OEMs requiring compact solutions for complex lighting architectures.

Replacement Considerations

The A6274KLPTR-T is listed as a parameter-equivalent substitute. Verify if the packaging difference affects assembly processes. No other direct substitutes are documented in the provided source material.
