Overview
The IS32LT3124D-ZLA3-TR is a quad-channel linear LED driver IC from Lumissil Microsystems, designed for constant current applications. It features dynamic headroom control (DHC) and fault reporting with a 4.8V threshold. The device supports PWM dimming and implements an 'one-fail-all-fail' protection strategy. It operates within a supply voltage range of 5 V to 28 V and delivers an output current of 150 mA per channel. The component is housed in an 8-TSSOP package.
Feature Summary
- Quad-channel linear architecture with dynamic headroom control
- Integrated fault reporting with 4.8V threshold detection
- One-fail-all-fail protection mechanism for system reliability
- Supports PWM dimming for brightness control
Applications
- Constant current LED lighting systems
- Commercial general lighting fixtures
- Residential LED drivers
- Automotive interior lighting applications
Procurement Notes
Verify the specific suffix ZLA3-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution data may vary. Ensure compatibility with existing PCB footprints for the 8-TSSOP package. Check for any recent Product Change Notifications regarding manufacturing updates or material changes before finalizing procurement orders.
Selection Notes
Select this component when a multi-channel linear solution with integrated fault management is required. The 4.8V threshold provides specific over-voltage protection characteristics distinct from other variants like the 1.22V threshold version. Consider the 150 mA output capability and 8-TSSOP form factor for space-constrained designs requiring four independent LED channels with synchronized fail-safe behavior.
Part Context
This part belongs to the IS32LT3124 series of quad-channel linear LED drivers from Lumissil Microsystems. The series offers flexibility through different fault thresholds and packaging options. The IS32LT3124D variant specifically utilizes an 8-TSSOP package, distinguishing it from other series members that may use eTSSOP-16 packages. It is part of Lumissil's broader portfolio addressing commercial, residential, and automotive lighting markets.
Replacement Considerations
The IS32LT3124F-ZLA3-TR is a related quad-channel linear driver but features a 1.22V fault threshold and an eTSSOP-16 package, requiring significant design changes. Direct pin-to-pin replacement is not feasible due to the package difference. Verify if the lower fault threshold meets application requirements if considering alternative series members.
