IS32LT3124F-ZLA3-TR

Overview

The IS32LT3124F-ZLA3-TR is a quad-channel linear LED driver IC from Lumissil Microsystems, designed for constant current applications. It operates within a supply voltage range of 5 V to 28 V and delivers an output current of 150 mA per channel. The device supports PWM dimming and utilizes Boost or Buck topologies. It is housed in a 16-pin eTSSOP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

Integrates dynamic headroom control (DHC) to optimize power efficiency.
Provides fault reporting with a specific 1.22V threshold detection.
Features isolated failure handling where only the failed channel is disabled.
Supports open LED protection mechanisms.

Applications

Automotive lighting systems
General LED illumination
Signaling displays

Procurement Notes

Verify the exact part number suffix against official Lumissil documentation to ensure correct packaging and tape specifications. Confirm that the 16-pin eTSSOP footprint matches your PCB layout requirements. Check for RoHS compliance status in the latest datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a four-channel solution with independent fault isolation is required. The 150 mA output current suits standard LED arrays. Ensure the input voltage stays within the 5 V to 28 V range. Consider the thermal performance in the eTSSOP-16 package for your specific ambient conditions.

Part Context

This part belongs to the IS32LT3124F series of linear LED drivers. It complements other Lumissil offerings like the IS32LT3138 and IS32LT3146 by providing a dedicated quad-channel option. The series focuses on automotive and industrial reliability with integrated protection features.
