Overview
The TLC5941PWPG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It features individually adjustable 4096-step grayscale PWM brightness control for each channel. The device operates within a supply voltage range of 3 V to 5.5 V and supports an output voltage up to 17 V. Each channel provides a maximum output current of 80 mA. It utilizes a shift register interface for data input and includes internal error flagging, fault detection, and LED open/short detection capabilities. The component is housed in a 28-HTSSOP package.
Feature Summary
- Provides 16 channels of constant-current sinking with individual 4096-step grayscale PWM control
- Integrates dot correction and error flagging for enhanced display accuracy
- Includes built-in fault detection mechanisms for LED open and short circuit conditions
Applications
- Display backlighting systems
- Signage applications
- General LED indicator arrays
Procurement Notes
Verify the specific ordering suffix 'G4' corresponds to lead-free and RoHS-compliant specifications as defined by Texas Instruments. Confirm that the HTSSOP-28 package variant matches the required PCB footprint and thermal management requirements for the target application environment. Ensure compatibility with the system's shift register clock and data rates.
Selection Notes
Select this component when 16 independent channels of constant-current drive are required with high-resolution grayscale control. It is suitable for designs needing integrated fault detection and dot correction without external microcontroller processing for PWM generation. Consider the 80 mA per channel limit and the 17 V output voltage ceiling relative to the LED string configuration.
Part Context
This part belongs to the TLC5941 series of LED drivers from Texas Instruments. It is functionally equivalent to the TLC5941PWP but may differ in packaging compliance or environmental certifications due to the G4 suffix. It serves as a dedicated driver for high-density LED displays requiring precise current regulation and dimming control.
Replacement Considerations
The TLC5941PWP is a direct functional substitute within the same family. Verify if the G4 suffix indicates specific regulatory compliance differences such as RoHS status compared to the standard PWP variant.
