Overview
The TLC5916IDG4 is an 8-bit constant-current LED sink driver manufactured by Texas Instruments. It features a serial interface for data input and provides eight independent output channels, each capable of sourcing up to 120 mA. The device operates within a supply voltage range of 3 V to 5.5 V and supports clock frequencies up to 30 MHz. It is housed in a 16-pin SOIC-Narrow package and functions reliably across an extended temperature range from -40°C to +125°C.
Feature Summary
- Provides eight independent constant-current output channels for precise LED control
- Integrates comprehensive fault detection including open LED, short-to-ground, and short-to-VLED diagnostics
- Utilizes a simple serial interface for efficient data transmission and shift register functionality
Applications
- General LED lighting systems requiring constant current regulation
- Signage and display applications needing reliable LED driving
- Industrial control panels with high-temperature operational requirements
Procurement Notes
Verify the specific ordering suffix 'DG4' corresponds to the SOIC-Narrow 16-pin package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the selected component matches the required thermal performance specifications for the intended operating environment before finalizing procurement orders.
Selection Notes
Select this component for designs requiring eight individually addressable LED channels with integrated fault protection. Consider the 120 mA per channel limit and the 3 V to 5.5 V supply range during circuit planning. The SOIC-Narrow package is suitable for surface-mount assembly processes requiring standard footprint compatibility.
Part Context
This part belongs to the TLC5916 series of constant-current LED sink drivers from Texas Instruments. It shares functional similarities with other variants in the family but differs in packaging and specific pinout configurations. The series is designed for applications demanding reliable LED illumination with diagnostic capabilities.
Replacement Considerations
TLC5916ID is a manufacturer-recommended alternative offering identical electrical characteristics. Verify package compatibility and marking differences when substituting.
