TLC69652QPWPRQ1

Overview

The TLC69652QPWPRQ1 is an automotive-grade LED matrix local dimming backlight driver designed for high-performance display applications. It features a 32-channel integrated current sink architecture, providing precise control over individual LED segments. The device supports a maximum output current of 30 mA per channel and operates within a supply voltage range of 3 V to 5.5 V. It utilizes a PWM topology for dimming control and functions at a working frequency of 20 MHz. The component is housed in a 28-pin HTSSOP package and is rated for operation across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding automotive environments.

Feature Summary

• Integrates 32 independent current sinks for precise mini-LED matrix local dimming control
• Supports PWM dimming topology with integrated current regulation capabilities
• Automotive-grade construction compliant with AEC-Q100 standards for enhanced durability

Applications

• Automotive instrument cluster displays requiring localized brightness adjustment
• Infotainment system backlighting with high dynamic range requirements
• Advanced driver assistance system (ADAS) visual interfaces

Procurement Notes

Verify the specific suffix 'PWPRQ1' to confirm the HTSSOP-28 package type and reel packaging configuration. Ensure that the procurement order explicitly references the Q1 designation to guarantee compliance with automotive quality standards and functional safety requirements. Cross-reference the manufacturer datasheet for moisture sensitivity levels and recommended soldering profiles prior to assembly integration.

Selection Notes

Select this component when designing systems requiring granular control over large LED arrays with minimal external circuitry. The integrated 32-channel sink reduces board space compared to discrete solutions. Consider the 30 mA output limit and 50 V drain voltage capability when sizing the LED matrix. Evaluate thermal management strategies given the dense channel count within the compact HTSSOP-28 footprint.

Part Context

This part belongs to the Texas Instruments TLC6965x series of automotive LED drivers. It is specifically engineered for complex lighting architectures where local dimming enhances contrast and efficiency. The device complements other family members like the TLC69650 and TLC69662 by offering a higher channel count suitable for detailed image rendering in vehicle displays.

Replacement Considerations

Direct substitutes within the same family include the TLC69650QPWPRQ1 for reduced channel counts or the TLC69662QPWPRQ1 for different current specifications. Verify pin compatibility and electrical parameters before swapping components to ensure design integrity.
