TLC5916IPW

Overview

The TLC5916IPW 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 TSSOP package with a thermal operating range from -40°C to +125°C. Key electrical specifications include a maximum power dissipation of 1 W and a maximum supply current of 22 mA.

Feature Summary

• Provides eight independent constant-current output channels for precise LED control.
• Integrates fault detection capabilities including open LED, short-to-ground, and short-to-VLED diagnostics.
• Utilizes a simple serial interface for efficient data transmission and shift register functionality.
• Includes thermal shutdown protection to safeguard the device during over-temperature conditions.

Applications

• Signage and display systems requiring individual LED segment control
• General-purpose LED lighting applications
• Industrial indicator panels

Procurement Notes

Verify that the specific part number suffix matches the required package type and temperature grade. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations. Ensure that the ordering information aligns with the intended application environment and regulatory requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring multiple individually addressable LED outputs with high current capability. Consider the TSSOP package constraints for PCB layout and thermal management. Evaluate the need for fault detection features if system reliability is critical. Compare against other drivers in the series based on channel count and interface requirements.

Part Context

This component belongs to the TLC5916 family of LED drivers designed for versatile lighting control applications. It serves as a linear constant-current sink driver, offering a balance between performance and simplicity. The device is commonly used in scenarios where precise current regulation is necessary for consistent LED brightness across multiple channels.

Replacement Considerations

TLC5916IPWRG4 is a verified equivalent variant within the same product line, differing primarily in packaging format while maintaining identical functional specifications and electrical characteristics.
