TLC5923RHBT

Overview

The TLC5923RHBT is a Texas Instruments LED display driver featuring 16 constant-current channels. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum clock frequency of 30 MHz. The device delivers an output current of up to 50 mA per channel with a maximum output voltage of 32 V. Packaged in a 32-VQFN (5x5 mm) housing, it functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates 16-channel dot correction for uniform brightness
• Supports grayscale PWM control via serial interface
• Includes thermal shutdown protection

Applications

• LED backlighting systems
• General LED indicator arrays
• Portable electronic displays

Procurement Notes

Verify the specific suffix 'RHBT' against the manufacturer's official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system voltage limits and thermal requirements before integration. Cross-reference RoHS compliance status using the latest component documentation provided by Texas Instruments.

Selection Notes

Select this component when 16 individually addressable constant-current outputs are required. It is suitable for designs needing precise grayscale control without external multiplexing. Consider the VQFN package size for space-constrained PCB layouts. Verify that the 50 mA channel current meets the target LED forward current requirements.

Part Context

This part belongs to the TLC592x series of LED drivers from Texas Instruments. It provides a cost-effective solution for driving multiple LEDs with consistent current levels. The series is designed for applications requiring high reliability and simple serial control interfaces.
