TLC6C598QPWRQ1

Overview

The TLC6C598QPWRQ1 is an automotive-grade, monolithic, medium-voltage, low-current power 8-bit shift register designed for LED driver applications. It features eight power DMOS transistor outputs capable of delivering 50 mA continuous current at VCC = 5 V or 200 mA at higher voltages, with a maximum output rating of 40 V. The device operates within an ambient temperature range of -40°C to 125°C and holds AEC-Q100 Grade 1 qualification. Packaged in a 16-TSSOP surface-mount format, it integrates serial input capabilities for efficient control in instrumentation clusters and tell-tale lamp systems.

Feature Summary

• Integrates eight independent power DMOS outputs for direct LED driving
• Supports high-current sink capability up to 200 mA per channel
• Features automatic direction detection for bidirectional data transfer
• Complies with AEC-Q100 Grade 1 standards for automotive reliability

Applications

• Instrumentation cluster displays
• Tell-tale lamp indicators
• LED illumination and control systems
• Automotive exterior lighting modules

Procurement Notes

Verify the specific suffix 'PWRQ1' confirms the 16-TSSOP package and automotive grade status. Ensure compatibility with system voltage levels, as outputs support up to 40 V. Confirm that the design accounts for thermal dissipation given the 200 mA continuous current capability. Cross-reference the datasheet revision to ensure alignment with current manufacturing specifications and AEC-Q100 certification requirements before finalizing procurement.

Selection Notes

Select this component when designing automotive LED systems requiring moderate load power with high current density per channel. The 8-bit shift register architecture simplifies interface requirements by reducing pin count compared to parallel drivers. Consider the 40 V output rating for driving series LED strings. The wide operating temperature range ensures functionality in harsh automotive environments without additional thermal management components.

Part Context

This part belongs to the Texas Instruments TLC6C59x-Q1 family of Power Logic 8-bit shift register LED drivers. These devices are engineered for automotive applications where space efficiency and high output current are critical. The family shares common architectural features but varies in package options and specific electrical characteristics to suit different board layout constraints and load requirements.

Replacement Considerations

TLC6C598CQDRQ1 offers similar functionality in a smaller QFN package. TLC6C598QPWRQ1 is the primary equivalent in the same TSSOP form factor. Verify pinout compatibility and thermal performance when substituting between package types.
