TLC6C598CQDRQ1

Overview

The TLC6C598CQDRQ1 is an automotive-grade, monolithic, medium-voltage power logic 8-bit shift register designed for LED display and lighting applications. It features eight power DMOS transistor outputs capable of delivering 50 mA continuous current at VCC = 5 V or 200 mA at lower voltages. The device operates with a supply voltage range of 3 V to 5.5 V and supports output voltages up to 40 V. Packaged in a 16-SOIC surface-mount case, it meets AEC-Q100 qualification standards and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates eight high-current power DMOS outputs for direct LED driving without external transistors
• Supports PWM dimming control for precise brightness adjustment in automotive lighting systems
• Provides robust electrical isolation with a maximum output rating of 40 V for medium-voltage loads

Applications

• Automotive exterior lighting modules including headlights and taillights
• Interior ambient lighting and dashboard display illumination
• LED matrix displays requiring moderate load power and shift register control

Procurement Notes

Verify the complete part number including suffixes such as CQDRQ1 to ensure correct package type, temperature grade, and automotive qualification status. Confirm that the specific revision matches the design requirements for voltage ratings and pinout compatibility. Check manufacturer documentation for any recent product change notices affecting assembly or sourcing locations before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated power switching with serial data input capabilities. It is suitable for applications needing individual channel control with high current density per output. Consider the 16-SOIC package constraints for thermal management and PCB layout space. Ensure the host controller provides compatible SPI or standard shift register timing signals for reliable data transmission.

Part Context

This device belongs to the Texas Instruments TLC6C598 family of power logic shift registers. It is specifically engineered for automotive environments, distinguishing itself from commercial variants through enhanced reliability testing and extended temperature operation ranges. The Q1 suffix indicates compliance with automotive quality standards, making it appropriate for safety-critical vehicle electronics where long-term durability is essential.

Replacement Considerations

Check for direct cross-reference part numbers from Texas Instruments within the same TLC6C59x series. Verify pin-to-pin compatibility if substituting with other 8-bit shift register drivers. Ensure alternative components meet the same AEC-Q100 grade and voltage specifications for automotive integration.
