TLC69662QPWPRQ1

Overview

The TLC69662QPWPRQ1 is an automotive-grade LED lighting driver IC designed for 32 mini-LED matrix local dimming backlight applications. It features a 16-channel output architecture with independent PWM dimming control per channel. The device supports an input voltage range of 3 V to 5.5 V, delivering up to 60 mA output current and handling output voltages up to 50 V. Operating within a temperature range of -40°C to +125°C, it utilizes a 28-pin HTSSOP package.

Feature Summary

• Provides independent 16-channel PWM dimming control for precise local dimming in mini-LED matrices
• Automotive qualification compliant for high reliability in vehicle environments
• Integrates shift register functionality for simplified serial data interface

Applications

• Automotive interior ambient lighting systems
• Mini-LED display backlight units requiring local dimming
• High-end automotive instrument clusters and infotainment screens

Procurement Notes

Verify the complete part number including suffixes such as PWPRQ1 to ensure correct packaging and automotive grade specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD protection measures are observed during handling due to moisture sensitivity classification.

Selection Notes

Select this component when designing automotive displays requiring localized brightness control rather than global dimming. The 16-channel configuration suits half-matrix or specific zone dimming strategies. Verify that the system power supply remains within the 3 V to 5.5 V input range and that thermal management accommodates the HTSSOP package constraints at maximum load.

Part Context

This device belongs to the TLC69662 series of LED drivers from Texas Instruments. It is specifically engineered for automotive applications, distinguishing itself from consumer-grade counterparts through extended temperature ratings and robustness standards required for vehicular electronics.

Replacement Considerations

Check for direct substitutes within the same family, such as non-automotive variants like TLC69662RTWR, noting differences in operating temperature ranges and qualification standards.
