IS31FL3733B-TQLS4-TR

Overview

The IS31FL3733B-TQLS4-TR is an LED driver IC featuring a 12x16 dot matrix configuration with individual auto-breath functionality. It utilizes a 48-pin eTQFP (7x7mm) package and operates on a 5V supply voltage. The device supports I2C and PWM dimming interfaces, delivering a constant current of 42mA per output across 28 channels.

Feature Summary

Supports 12x16 dot matrix LED driving with individual auto-breath function
Integrates I2C compatible interface for programming and control
Provides linear constant current output capability

Applications

Dot matrix LED displays
LED lighting development tools
Automotive intelligent signaling displays

Procurement Notes

Verify the specific suffix TQLS4 to confirm the 48-pin eTQFP package variant. Confirm the operating temperature range and compliance status against the official datasheet before integration. Ensure the I2C address configuration matches the system design requirements.

Selection Notes

Select this component for applications requiring a 12x16 matrix layout with integrated breath effects. Compare pin compatibility with the QFLS4 variant if board space constraints differ. Validate that the 42mA output current meets the specific LED forward current requirements of the target display module.

Part Context

This part belongs to the IS31FL3733 series of general-purpose LED matrix drivers. It shares core architecture with variants like the IS31FL3733-QFLS4-EB evaluation board but differs in package type and reel packaging format. The series targets high-pixel count displays with efficient power management.

Replacement Considerations

The IS31FL3733-QFLS4-TR is a direct functional substitute with identical electrical characteristics but utilizes a QFN-48 package instead of the eTQFP-48 form factor.
