IS32LT3129A-ZLA3-TR

Overview

The IS32LT3129A-ZLA3-TR is a triple-channel linear LED driver IC designed for automotive lighting applications. It operates within an input voltage range of 5 V to 42 V and delivers up to 150 mA output current per channel. The device supports PWM dimming and features fade-in/fade-out functionality. Packaged in a 20-pin eTSSOP with exposed pad, it functions reliably between -40°C and +125°C. Key electrical parameters include a maximum power dissipation of 2.94 W and a maximum supply current of 6.6 mA.

Feature Summary

Triple-channel constant current output capability
Integrated PWM dimming control interface
Automotive-grade reliability with extended temperature range

Applications

Automotive interior lighting systems
Daytime running light circuits
General automotive illumination modules

Procurement Notes

Verify the specific suffix ZLA3-TR against official Lumissil documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure compatibility with AEC-Q100 automotive qualification requirements if specified for your design. Cross-reference the exact part number with manufacturer datasheets to validate pinout and thermal characteristics before finalizing procurement.

Selection Notes

Select this component when a compact solution for driving multiple LEDs with precise current regulation is required. The linear topology suits applications where efficiency is secondary to cost and simplicity. Verify that the 42 V input limit accommodates your system's transient voltage spikes. Consider the 20-pin package size for PCB layout constraints.

Part Context

This part belongs to the IS32LT series of linear LED drivers from Lumissil Microsystems. The series targets automotive markets with integrated protection features. The IS32LT3129A variant specifically offers three channels, distinguishing it from single or quad-channel counterparts in the same family.

Replacement Considerations

Check for direct substitutes like the IS32LT3128A for triple-channel needs or IS32LT3124B for quad-channel requirements. Verify pin-to-pin compatibility and electrical specifications before substitution.
