TLC5946RHBTG4

Overview

The TLC5946RHBTG4 is a 16-channel, 12-bit PWM LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and features a maximum power dissipation of 3.482 W. The device provides a low-level output current of 5 mA and a high-level output current of -1 mA, with a maximum supply current of 45 mA. It is housed in a 32-VQFN package and supports surface-mount installation. The component functions across an operating temperature range from -40°C to +85°C.

Feature Summary

Integrates 6-bit dot correction for precise individual LED brightness uniformity.
Includes fault detection capabilities for identifying open or shorted LED conditions.
Provides error flagging to indicate internal status issues during operation.

Applications

LED backlighting systems
Digital signage displays
General LED indicator arrays

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance when sourcing. Confirm the 32-VQFN package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications. Check datasheet details for moisture sensitivity level handling procedures prior to assembly.

Selection Notes

Select this component for designs requiring 16 independent channels with high-resolution dimming control. The integrated dot correction simplifies calibration processes for display uniformity. Consider the thermal performance given the specified power dissipation limits. Verify interface compatibility with the host microcontroller for data transmission.

Part Context

This part belongs to the TLC5946 series of LED drivers from Texas Instruments. It shares core functionality with variants like the TLC5946RHBR and TLC5946PW, differing primarily in packaging and manufacturing revision codes. The series is designed for applications needing multiple synchronized LED outputs with programmable brightness levels.

Replacement Considerations

The TLC5946RHBR is a direct functional equivalent within the same series. The TLC5946PW serves as a legacy alternative but utilizes a different TSSOP package. Verify pinout compatibility and thermal characteristics when substituting these parts.
