TLC5927QPWPRQ1

Overview

The TLC5927QPWPRQ1 is an automotive-grade, 16-bit constant-current LED sink driver manufactured by Texas Instruments. It operates within a supply voltage range of 3 V to 5.5 V and supports output currents up to 120 mA per channel. The device features a linear shift register for dimming control and is housed in a 24-pin HTSSOP package. Designed for high reliability, it functions across an extended temperature range from -40°C to +125°C and meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Provides 16 channels of constant-current sinking for precise LED brightness control
• Integrates a linear shift register for serial data input and dimming management
• Qualified for automotive environments with extended industrial temperature operation

Applications

• Automotive interior ambient lighting systems
• Instrument cluster backlighting drivers
• Dashboard display illumination control

Procurement Notes

Verify the Q suffix indicates automotive qualification and PWPR denotes the specific HTSSOP-24 tape-and-reel packaging configuration. Confirm that the component meets AEC-Q100 standards required for your specific vehicle grade. Ensure design compatibility with the 3 V to 5.5 V supply rail and check moisture sensitivity levels for reflow soldering profiles prior to procurement.

Selection Notes

Select this component when a high-channel-count, low-voltage LED sink driver is required for automotive displays. It is suitable for designs needing serial interface simplicity and uniform current regulation across multiple LEDs. Consider thermal dissipation requirements given the 120 mA per channel capability in a compact surface-mount package.

Part Context

This part belongs to the TLC5927 family of constant-current LED drivers. The 'Q' prefix signifies automotive qualification, while 'PWPR' identifies the 24-lead HTSSOP package with tape-and-reel shipping. It serves as a specialized solution for multi-zone lighting control in vehicles where space constraints and reliability are critical factors.

Replacement Considerations

Direct substitutes include other automotive-qualified 16-channel LED sink drivers from Texas Instruments or compatible vendors offering identical pinouts and electrical characteristics. Verify that any replacement maintains the same shift register interface and current sourcing capabilities.
