TLC5916ID

Overview

The TLC5916ID is an eight-channel constant-current LED sink driver manufactured by Texas Instruments. It operates on a single power supply ranging from 3 V to 5.5 V and delivers up to 120 mA per channel with a maximum output voltage of 20 V. The device features a serial interface supporting clock frequencies up to 30 MHz. Packaged in a 16-pin SOIC-Narrow (D) format, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates eight independent constant-current sinks for uniform LED brightness control
• Includes thermal shutdown circuitry to protect against overheating conditions
• Supports high-speed serial data input via standard SPI-compatible interfaces

Applications

• LED backlighting systems for displays
• General-purpose LED indicator arrays
• Portable electronic device illumination

Procurement Notes

Verify the specific package variant, as the ID suffix denotes a 16-pin SOIC-Narrow tube. Confirm RoHS compliance status through official datasheets or manufacturer documentation before integration. Ensure the design accommodates the specified thermal operating limits and voltage constraints for reliable operation.

Selection Notes

Select this component when eight individually addressable constant-current outputs are required within a narrow surface-mount footprint. It is suitable for applications needing precise current regulation without external resistors per channel. Consider the SOIC-Narrow package dimensions and thermal dissipation capabilities relative to the total load current and ambient environment.

Part Context

Part of the TLC5916 family of LED drivers, designed for low-power applications requiring multiple channels. It serves as a cost-effective solution for managing LED arrays in consumer electronics where space is limited and consistent current drive is critical for display quality and longevity.
