Overview
The IS32LT3177-GRLA3-TR is a linear constant current LED driver manufactured by Lumissil Microsystems. It provides an output current of 200mA and supports 1kHz PWM dimming. The device is housed in an 8-SOP-EP package with dimensions of 5.0mm x 6.0mm. It operates within a temperature range of -40°C to +125°C and holds AEC-Q100 automotive qualification.
Feature Summary
- Linear constant current regulation for stable LED operation
- Integrated 1kHz PWM dimming capability
- Automotive-grade reliability with AEC-Q100 certification
Applications
- Automotive exterior lighting systems
- Automotive interior ambient lighting
- General high-reliability LED illumination
Procurement Notes
Verify the specific suffix GRLA3-TR against the official Lumissil datasheet to confirm pinout, thermal pad configuration, and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and soldering profile requirements for the SOP-8-EP package before finalizing procurement orders.
Selection Notes
Select this component when a single-channel linear driver with integrated PWM dimming is required for automotive applications. It is suitable for designs needing 200mA constant current without external MOSFETs. Consider alternative packages if board space constraints differ from the 8-SOP-EP form factor.
Part Context
This part belongs to the IS32LT31xx family of high-side linear LED drivers from Lumissil Microsystems. These devices are designed for general lighting applications in commercial, residential, and automotive markets, offering built-in protections and monolithic integration for extended life operation.
Replacement Considerations
Public documentation lists the IS32LT3178-GRLA3-TR as a substitute for the discontinued IS32LT3173 series; verify functional equivalence for the IS32LT3177 specifically through official Lumissil channels.
