TLC5952DAPR

Overview

The TLC5952DAPR is a Texas Instruments LED driver IC featuring 24 constant-current outputs housed in a 32-HTSSOP package. It operates on a supply voltage ranging from 3 V to 5.5 V with a maximum power dissipation of 3.9 W. The device supports a shift register topology and includes global brightness control alongside LED open-short detection capabilities.

Feature Summary

• Integrates 24 constant-current output channels for precise LED regulation
• Includes internal circuitry for detecting LED open and short conditions
• Supports global brightness adjustment via serial interface

Applications

• Signage displays
• LED lighting systems
• Dot matrix panels

Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging distinct from tube variants. Confirm HTSSOP-32 physical dimensions match PCB footprint requirements. Ensure ESD precautions are applied during handling due to moisture sensitivity classification.

Selection Notes

Select this component when 24 individually controlled constant-current channels are required within a single package. Evaluate thermal performance against the specified power dissipation limits. Consider the operating temperature range of -40°C to +85°C for environmental compatibility.

Part Context

This part belongs to the TLC5952 family of linear LED drivers manufactured by Texas Instruments. It provides a compact solution for driving multiple LEDs without external current-setting resistors, utilizing a standard serial interface for data input and latch control.

Replacement Considerations

TLC5952DAP serves as the tube-packaged equivalent of the same functional device.
