A6262KLPTR-T

Overview

The A6262KLPTR-T is a linear, programmable current regulator IC from Allegro MicroSystems designed for automotive LED lighting applications. It provides four independent output channels, each capable of delivering up to 100 mA. The device operates within a supply voltage range of 6 V to 50 V and supports PWM dimming for brightness control. It features internal switches and is housed in a 10-MSOP package with an exposed pad (EP). The component is qualified to AEC-Q100 standards and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

• Four independent linear current regulation channels providing precise LED control
• Supports pulse-width modulation (PWM) input for adjustable brightness dimming
• Integrated internal switches eliminate the need for external pass elements
• Automotive-grade qualification ensuring reliability under harsh environmental conditions

Applications

• Automotive interior lighting systems
• Exterior vehicle illumination modules
• Industrial high-brightness LED arrays
• Consumer LED lighting fixtures

Procurement Notes

Verify the specific suffix KLPTR-T against the official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, specifically the 10-MSOP-EP outline. Confirm that the design accounts for thermal dissipation requirements associated with linear regulation at the intended load currents. Check for any recent product change notices regarding packaging or material composition updates.

Selection Notes

Select this component when a multi-channel solution is required for low-to-medium current LED strings. The linear topology simplifies design by removing inductive components but requires careful thermal management. Compare against switching regulators if efficiency is critical, or single-channel drivers if fewer outputs are needed. Ensure the input voltage range aligns with the system's battery or power rail characteristics.

Part Context

This part belongs to the A6262 family of LED driver ICs from Allegro MicroSystems. The series focuses on providing reliable, linear current regulation for automotive and industrial markets. Similar parts in the lineup may offer different channel counts or current capabilities, such as the A6260 or A6268 variants, catering to diverse lighting architectures.

Replacement Considerations

The A6261KLYTR-T is documented as a parameter-equivalent substitute. Verify pinout compatibility and electrical specifications before substitution. Other members of the A626x family may serve as alternatives depending on channel count and current requirements.
