Overview
The IS31FL3733-TQLS4 is a 12x16 dot matrix LED driver IC manufactured by Lumissil Microsystems. It features an ARM Cortex-M3 core and operates on a 5 V supply voltage with a minimum operating temperature of -40 C. The device provides an output current of 2 A and is housed in a 48-eTQFP package measuring 7.0mm x 7.0mm. It supports I2C dimming and linear constant current control for individual LEDs.
Feature Summary
- Integrates an ARM Cortex-M3 core for advanced control capabilities
- Supports I2C compatible interface for programming and dimming
- Provides linear constant current output for individual LED regulation
Applications
- Dot matrix LED display systems
- LED lighting development tools
- Automotive intelligent signaling displays
Procurement Notes
Verify the specific suffix TQLS4 to confirm the eTQFP-48 package variant, as other suffixes like QFLS4 indicate different packages. Confirm RoHS compliance status through official documentation before integration. Ensure the 5 V supply requirement aligns with system design constraints.
Selection Notes
Select this component when a 12x16 matrix configuration with integrated microcontroller processing is required. The eTQFP-48 package suits applications needing surface mount assembly with specific thermal or pin-out requirements. Verify compatibility with I2C bus speeds and available GPIO resources on the host system.
Part Context
This part belongs to the IS31FL3733 series of LED drivers designed for high-density matrix applications. It shares functional similarities with variants like the IS31FL3733-QFLS4-TR but differs in package type. The series targets automotive and industrial display solutions requiring precise current control and programmable patterns.
Replacement Considerations
The IS31FL3733-QFLS4-TR serves as a package-compatible alternative if the QFN-48 form factor is acceptable. Verify pin-to-pin compatibility and software register mapping before substitution. Other series members may lack the specific ARM Cortex-M3 integration found in this model.
