Overview
The TLC5916IDR is an eight-channel constant-current LED sink driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output current of 120 mA per channel. The device features an internal boost topology, enabling an output voltage up to 20 V. It utilizes a serial interface with a maximum clock frequency of 30 MHz for data input. The component is housed in a 16-pin SOIC-Narrow package and is rated for operation between -40°C and +125°C.
Feature Summary
- Integrates an internal boost converter to drive LEDs requiring voltages higher than the supply rail.
- Provides individual constant-current control for each of the eight output channels.
- Includes thermal shutdown protection to safeguard the device during over-temperature conditions.
Applications
- LED backlighting systems
- General-purpose LED indicator arrays
- Portable electronic display modules
Procurement Notes
Verify the specific suffix 'IDR' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the SOIC-Narrow-16 footprint matches the target PCB layout. Ensure the design accounts for the 120 mA per-channel limit and total power dissipation constraints under maximum load conditions.
Selection Notes
Select this component when eight individually controllable constant-current sinks are required with integrated boost capability. It is suitable for designs needing high brightness control without external inductors. Consider the 30 MHz serial interface speed for refresh rate requirements. Evaluate thermal performance if operating near the upper temperature limits.
Part Context
This part belongs to the TLC5916 family of LED drivers from Texas Instruments. It shares functional similarities with the TLC5917 but differs in specific pinout or feature configurations. The series is designed for applications requiring precise LED current regulation and simplified system architecture through integrated power management.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before considering alternative components from other manufacturers.
