TLC5970RHPT

Overview

The TLC5970RHPT is a Texas Instruments LED display driver featuring three channels with 16-bit grayscale and 24-bit color depth. It utilizes Enhanced Serial Pulse Width Modulation (ES-PWM) for high-fidelity output. The device operates within a supply voltage range of 3.1 V to 3.5 V, with a maximum power dissipation of 3.106 W. It supports an operating temperature range from -40°C to +85°C and is housed in a 28-QFN package.

Feature Summary

• Integrates internal grayscale clock generation for simplified system timing.
• Provides fault detection capabilities including LED open circuit monitoring.
• Delivers precise PWM control for accurate RGB color reproduction.

Applications

• RGB LED matrix displays
• High-density LED signage
• Architectural lighting control systems

Procurement Notes

Verify the specific suffix RHPT corresponds to the 28-QFN package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management strategies align with the specified power dissipation limits during operation.

Selection Notes

Select this component for applications requiring multi-channel RGB control with high resolution. Consider the 28-QFN form factor for compact board layouts. Validate that the input signal interface matches the ES-PWM requirements defined in the technical specifications.

Part Context

This part belongs to the TLC5971 series family, designed for advanced LED driving needs. It shares functional similarities with other models in the lineup but differs in channel count and package configuration. The device serves as a specialized solution for complex lighting architectures requiring precise dimming control.

Replacement Considerations
