Overview
The TLC5929DBQR is a Texas Instruments LED lighting driver IC featuring 16 constant current outputs. It utilizes a linear topology with an internal shift register for dimming control. The device operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output current of 50 mA per channel. It is housed in a 24-pin SSOP package and functions at a clock frequency of up to 20 MHz. The component is rated for operation between -40°C and +85°C.
Feature Summary
- Provides 16-channel constant current regulation for uniform LED brightness.
- Integrates an internal shift register for serial data input and dimming control.
- Includes built-in open LED detection capabilities for fault monitoring.
Applications
- Signage illumination systems
- LED backlighting arrays
- General-purpose LED indicator panels
Procurement Notes
Verify the specific suffix DBQR confirms the tape-and-reel packaging format distinct from tube variants. Ensure the ordering part number matches the required 24-SSOP surface-mount package configuration. Confirm RoHS compliance status aligns with project environmental requirements before finalizing procurement orders.
Selection Notes
Select this component when 16 individually controllable constant current channels are required. It is suitable for designs needing linear regulation with low output voltage headroom. Consider the 20 MHz operating speed and SSOP footprint constraints during PCB layout planning.
Part Context
This part belongs to the TLC5929 series of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC5929RGET but differs in physical packaging. The series focuses on providing reliable constant current drive for multi-channel LED applications.
Replacement Considerations
TLC5929DBQ (Tube variant) offers identical electrical specifications but uses different packaging. TLC5929RGET provides the same functionality in a VQFN package. Verify pin compatibility and thermal performance when substituting across package types.
