Overview
The TLC59582RTQT is a 48-channel, 16-bit Enhanced Serial Pulse Width Modulation (ES-PWM) LED driver manufactured by Texas Instruments. It operates within a temperature range of -40°C to 85°C and utilizes a VQFN package with 56 pins. The device supports 16-multiplexing and includes integrated pre-charge FETs for enhanced reliability. Key features include LED open detection (LOD) and caterpillar canceling capabilities, designed for high-performance LED lighting applications requiring precise dimming control.
Feature Summary
- Supports 16-multiplexing for efficient channel management
- Includes integrated pre-charge FETs for improved reliability
- Features LED open detection (LOD) and caterpillar canceling
Applications
- LED lighting systems
- High-density LED displays
- Architectural lighting controls
Procurement Notes
Verify the specific suffix RTQT corresponds to the required tape-and-reel packaging configuration. Confirm that the 56-pin VQFN footprint matches the target PCB design. Ensure thermal management strategies align with the specified operating temperature range of -40°C to 85°C. Cross-reference the manufacturer part number with official distributor catalogs to confirm current production status and availability constraints.
Selection Notes
Select this component when 48 individually controllable channels are required with 16-bit resolution. The ES-PWM interface reduces pin count compared to parallel alternatives. Consider the integrated LOD and caterpillar canceling features if system reliability against LED faults is critical. Verify compatibility with the host controller's serial interface timing requirements.
Part Context
This part belongs to the Texas Instruments TLC5958x series of LED drivers. It shares functional similarities with the TLC59581 but offers increased channel density. The RTQ suffix indicates the specific VQFN package type and thermal characteristics. It serves as a direct replacement for legacy parallel LED drivers in modern compact designs.
Replacement Considerations
The TLC59582RTQR is a related variant within the same family, potentially differing in packaging or reel specifications. Verify pin-to-pin compatibility before substitution. Ensure that any alternative maintains the 16-bit ES-PWM interface and 48-channel output capability.
