TLC5923DAPR

Overview

The TLC5923DAPR is a 16-channel LED display driver manufactured by Texas Instruments, housed in an HTSSOP-32 package. It operates within a supply voltage range of 3 V to 5.5 V and supports a maximum power supply current of 65 mA. The device provides low-level output currents of 1 mA and high-level output currents of -1 mA. It functions across a temperature range from -40 °C to +85 °C and includes dot correction capabilities for uniform LED brightness.

Feature Summary

• Integrates dot correction functionality to ensure consistent LED intensity across all channels.
• Includes fault detection mechanisms with open LED detection and power good/error flag outputs.
• Supports serial interface control for efficient data transmission and channel configuration.

Applications

• LED matrix displays requiring precise current control
• Seven-segment or multi-digit numeric displays
• Status indicator arrays in consumer electronics

Procurement Notes

Verify the specific suffix 'DAPR' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'DAP'. Confirm RoHS compliance status through the official datasheet as distributor listings may vary. Ensure the operating environment stays within the specified -40 °C to +85 °C range to maintain performance integrity.

Selection Notes

Select this component when 16 individually addressable LED channels are required with built-in brightness correction. It is suitable for designs needing fault detection features like open LED sensing. Compare against the TLC5922 if error flags are unnecessary, or consider higher-current drivers if load requirements exceed 1 mA per channel.

Part Context

This part belongs to the TLC592x series of LED drivers from Texas Instruments. It shares architectural similarities with the TLC5922 but adds diagnostic features such as power good flags and open LED detection. The DAPR designation indicates a reel-based packaging format optimized for automated surface-mount assembly processes.

Replacement Considerations

TLC5923DAP (tube version) offers identical electrical characteristics but differs in packaging format. TLC5922DAPR serves as a functional substitute if fault detection features are not required. Verify pin compatibility and software register configurations before substituting any alternative models.

FAQ

Does the TLC5923DAPR support individual LED brightness adjustment?

Yes, it includes dot correction capabilities that allow for per-channel intensity adjustment to compensate for LED variations.

What diagnostic features are included in this driver?

The device provides open LED detection and a power good/error flag output to indicate system faults.
