TLC5924RHBR

Overview

The TLC5924RHBR is a 16-channel LED display driver manufactured by Texas Instruments, housed in a VQFN-32 package. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40 °C to +85 °C. The device features fault detection capabilities, including open and short circuit detection for LEDs. It utilizes a serial interface for data input and includes power good/error flag outputs. The component is designed for applications requiring precise LED control with integrated diagnostic features.

Feature Summary

• Integrates 16 constant-current sink channels for direct LED driving
• Provides hardware-based fault detection for open and shorted LED conditions
• Includes error flag output for system status monitoring
• Supports serial data input for simplified interface connectivity

Applications

• LED matrix displays
• Backlight control systems
• Indicator lighting arrays
• Portable electronic devices

Procurement Notes

Verify the specific suffix RHBR confirms the reel packaging variant against your assembly requirements. Confirm that the VQFN-32 footprint matches your PCB layout design. Ensure the -40 °C to +85 °C industrial temperature range meets your operational environment specifications. Cross-reference the datasheet for any recent product change notifications or lifecycle status updates prior to finalizing procurement.

Selection Notes

Select this component when a 16-channel solution with integrated fault detection is required. Compare against the TLC5924DAP if a tube-packaged HTSSOP-32 variant is preferred for prototyping. Consider the TLC5946 series if 12-bit PWM resolution is necessary instead of the standard configuration. Verify that the VQFN-32 package size fits within the available board space constraints.

Part Context

This part belongs to the TLC5924 family of LED drivers from Texas Instruments. It shares functional similarities with other members like the TLC5924DAP but differs in packaging and reel specifications. The RHBR suffix specifically denotes the tape and reel format suitable for automated surface-mount assembly processes.

Replacement Considerations

TLC5924DAP offers identical electrical functionality in a tube-packaged HTSSOP-32 format.
