Overview
The IS31FL3296-UTLS4-TR is an LED lighting driver IC manufactured by Lumissil Microsystems. It features a UTQFN-12 package with dimensions of 2mm x 2mm. The device supports 2-RGB and 6-LED configurations, providing 6 output channels. It operates within an input voltage range of 2.7 V to 5.5 V. The maximum output current per channel is 40 mA. The IC utilizes I2C communication and PWM dimming for control. It functions at a frequency of 440 Hz and supports surface mount installation.
Feature Summary
- Integrates 2-RGB and 6-LED drive capabilities in a compact footprint
- Supports PWM dimming via I2C serial interface
- Provides linear constant current regulation for LED outputs
Applications
- Compact consumer electronics lighting
- IoT device status indicators
- Small form-factor automotive interior lighting
Procurement Notes
Verify the specific package designation UTQFN-12 against design requirements, as it differs from the standard QFN variants found in the IS31FL3296 series. Confirm supply availability through authorized distributors, as stock levels may be limited. Ensure the I2C address configuration aligns with system bus constraints before finalizing procurement.
Selection Notes
Select this component when a minimal board area is critical due to its 2mm x 2mm UTQFN-12 package. It is suitable for applications requiring independent RGB and white LED control with low pin count. Consider the 40 mA output capability for direct driving of standard indicator LEDs without external transistors.
Part Context
This part belongs to the IS31FL3296 family of LED drivers from Lumissil Microsystems. While the standard IS31FL3296-QFLS4-TR uses a QFN-20 package, the UTLS4 variant utilizes a smaller UTQFN-12 package. Both share similar functional specifications regarding RGB and LED channel support.
Replacement Considerations
The IS31FL3296-QFLS4-TR serves as a functional equivalent but requires a QFN-20 footprint. Verify PCB layout compatibility when substituting between the UTQFN-12 and QFN-20 packages.
