Overview
The IS32FL3749-TQLA3-TR is a 24x4 Local Dimming Matrix LED Driver IC designed for mini LED backlight applications. It integrates 24 constant current channels capable of driving up to 60mA per channel, supporting high-resolution displays with artifact-free pixel control. The device features configurable matrix sizes and supports dithered PWM modes for smooth brightness adjustment. Communication is handled via selectable I2C or SPI interfaces, allowing flexible system integration. The component is supplied in a Tape & Reel (TR) package.
Feature Summary
- Supports 24x4 local dimming matrix configuration for mini LED backlights
- Integrates 24 constant current output channels with adjustable drive current
- Features selectable I2C or SPI bus interfaces for system communication
- Includes dithered PWM modes to minimize visual artifacts
Applications
- Mini LED backlight units for displays
- Automotive intelligent signaling displays
- High-pixel-count digital signage panels
Procurement Notes
Verify the specific ordering suffix and package type against the manufacturer's latest datasheet before procurement. Confirm that the TR packaging matches your automated assembly requirements. Check for any recent product change notices (PCN) regarding pinout or electrical characteristics. Ensure compatibility with your system's I2C or SPI voltage levels. Validate availability status as supply conditions may vary by region.
Selection Notes
Select this driver when a compact solution for small-scale local dimming matrices is required. It is suitable for designs needing independent channel control without external multiplexing. Consider the interface speed requirements when choosing between I2C and SPI modes. Evaluate the thermal performance of the PCB layout given the 60mA channel capability. Ensure the host controller can manage the addressable pixel count efficiently.
Part Context
This component belongs to Lumissil's IS32FL series of LED display drivers, which focus on high-density matrix configurations. The series is engineered for applications requiring precise current matching and low power consumption. The TQLA3-TR designation indicates the specific tape and reel packaging variant for surface-mount assembly processes.
Replacement Considerations
Check for direct substitutes within the IS32FL family that offer similar channel counts. Verify if alternative packages from the same manufacturer provide equivalent electrical specifications. Ensure any replacement maintains compatibility with existing firmware and hardware interfaces.
