TLC5917IDR

Overview

The TLC5917IDR 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 delivers up to 120 mA per channel. The device features a boost topology with a maximum output voltage of 20 V and supports a clock frequency of 30 MHz. It includes thermal shutdown protection and is housed in a 16-SOIC package, suitable for operation between -40°C and +125°C.

Feature Summary

Provides eight independent constant-current sinks for uniform LED brightness control
Integrates internal boost converter to drive LEDs requiring higher voltages than the supply rail
Includes thermal shutdown circuitry to protect the device from overheating conditions

Applications

Signage displays
LED backlighting systems
General indicator lighting

Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-16 narrow package and tape-and-reel delivery format. Confirm RoHS compliance status and ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement specifications.

Selection Notes

Select this component when eight individually controllable constant-current outputs are required. Ensure the external inductor and diode ratings support the boost topology for the intended LED string voltage. Verify that the 120 mA per-channel current capability aligns with the LED specifications and that the SOIC-16 package fits the PCB layout constraints.

Part Context

This part belongs to the TLC5917 series of LED drivers. It shares functional similarities with other members like the TLC5917IPW but differs in packaging. The series is designed for applications requiring precise current regulation across multiple channels without complex external programming.

Replacement Considerations

The TLC5917IPW serves as a pin-compatible alternative offering the same electrical performance in a TSSOP-16 package. Verify footprint compatibility and thermal dissipation characteristics when substituting between SOIC and TSSOP packages.
