Overview
The TLC5923DAPRG4 is a 16-channel constant-current sink LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3.0 V to 5.5 V and supports a data transfer rate of 30 MHz. Each channel features an On/Off state and provides 128-step adjustable constant current sink capability through dot correction. The device is housed in a HTSSOP-32 package with exposed pad, designed for surface-mount installation.
Feature Summary
- Provides 16 independent channels for constant-current sinking applications
- Includes per-channel dot correction with 128-step adjustability for uniformity
- Supports high-speed serial data input at 30 MHz transfer rates
Applications
- LED display panels requiring precise current control
- Backlighting systems for LCD modules
- General-purpose LED indicator arrays
Procurement Notes
Verify the complete part number including the G4 suffix to ensure compliance with RoHS standards and lead-free manufacturing requirements. Confirm that the HTSSOP-32 package variant matches your PCB footprint design. Check official Texas Instruments documentation for specific thermal dissipation guidelines associated with the exposed pad configuration during integration.
Selection Notes
Select this component when a fixed 16-channel solution with integrated dot correction is required. Ensure the system power supply remains within the 3.0 V to 5.5 V operational window. Consider the 30 MHz interface speed if driving large displays or requiring rapid refresh rates without external multiplexing logic.
Part Context
This device belongs to the TLC592x family of LED drivers from Texas Instruments. It shares functional similarities with the TLC5922 but offers increased channel count. The DAPG4 designation indicates the specific HTSSOP-32 package and environmental compliance status, distinguishing it from tube-packaged variants like the TLC5923DAPG.
Replacement Considerations
The TLC5923DAPG serves as a non-green alternative in tube packaging. For pin-compatible upgrades with additional features such as fault detection, consider the TLC5946 series. Verify electrical parameters against the TLC5922 if channel count reduction is acceptable.
