TLC69661QPWPRQ1

Overview

The TLC69661QPWPRQ1 is an automotive-grade, 16-channel constant current sink driver designed for LED matrix applications. It integrates SRAM for brightness storage and supports PWM dimming. The device operates on a supply voltage of 3 V to 5.5 V and delivers up to 60 mA per channel with a maximum output voltage of 50 V. It functions within a temperature range of -40°C to +125°C and utilizes a 28-pin HTSSOP package.

Feature Summary

• Integrates sixteen independent constant current sinks with onboard SRAM for persistent brightness data storage.

Applications

• Automotive mini-LED matrix local dimming backlight systems

Procurement Notes

Verify the specific suffix 'QPWPRQ1' against official Texas Instruments documentation to confirm the HTSSOP-28 package, reel quantity, and AEC-Q100 qualification status. Ensure the ordering information matches the required moisture sensitivity level and reflow soldering profile specifications defined in the manufacturer's datasheet.

Selection Notes

Select this component when designing automotive displays requiring precise per-channel current control and non-volatile brightness retention via integrated SRAM. It is suitable for high-density LED arrays where individual channel regulation is necessary. Confirm that the 50 V output compliance and 60 mA drive capability align with the target LED forward voltage and current requirements.

Part Context

This part belongs to the TLC696x1-Q1 family of 16-channel constant current sink drivers. It shares architectural similarities with other members like the TLC69662QPWPRQ1 but is distinct in its specific integration of SRAM for brightness storage, differentiating it from standard sink drivers without memory features.
