TLC5924RHBT

Overview

The TLC5924RHBT is a Texas Instruments LED display driver featuring sixteen constant current outputs. It operates on a 3 V to 5.5 V supply and utilizes a 30 MHz shift clock frequency. The device provides up to 90 mA output current per channel with a maximum sink voltage of 15 V. Packaged in a 32-pin VQFN (5x5 mm) format, it supports serial data input for daisy-chaining. Key electrical parameters include a 3.3 V logic interface compatibility and thermal shutdown protection.

Feature Summary

• Integrates fault detection mechanisms including LED open circuit and short circuit identification.
• Provides power good and error flag signals for system status monitoring.
• Supports high-speed serial data shifting at frequencies up to 30 MHz.
• Features thermal shutdown protection to safeguard against overheating conditions.

Applications

• LED matrix displays
• Segmented LED indicators
• Portable electronic devices

Procurement Notes

Verify the specific package suffix RHBT corresponds to the required VQFN-32 configuration. Confirm that the component lifecycle status aligns with project requirements, as availability may be limited. Ensure that the operating temperature range meets the environmental specifications of the target application before finalizing procurement orders.

Selection Notes

Select this component when sixteen individually addressable constant current channels are required within a compact footprint. Consider the 15 V maximum sink voltage limit when designing LED string configurations. Evaluate the 30 MHz clock speed against the desired refresh rate and data throughput requirements of the display system architecture.

Part Context

This part belongs to the Texas Instruments TLC5924 series of LED drivers. It serves as a linear shift register solution for driving multiple LEDs without external components. The device simplifies PCB layout by integrating current regulation and control logic into a single integrated circuit suitable for space-constrained designs.
