TLC6C598PWR

Overview

The TLC6C598PWR is a monolithic, medium-voltage, low-current 8-bit shift register designed for LED driving applications. It features eight power DMOS transistor outputs capable of delivering 50 mA continuous current at VCC = 5 V. The device operates with a wide supply voltage range from 3 V to 5.5 V and supports an output maximum rating of 40 V. It utilizes standard SPI-compatible serial input for data shifting.

Feature Summary

• Eight parallel power DMOS outputs for direct LED connection
• SPI-compatible serial interface for simplified control
• Wide operating supply voltage range supporting 3 V to 5.5 V
• High output voltage tolerance up to 40 V

Applications

• Automotive exterior lighting systems
• Interior ambient LED illumination
• General-purpose LED matrix displays
• Industrial indicator panels

Procurement Notes

Verify the specific suffix 'PWR' indicates the TSSOP-16 package variant when sourcing. Confirm automotive qualification requirements if deploying in AEC-Q100 environments, as non-qualified variants may lack extended temperature or reliability certifications. Ensure supply voltage limits are respected during integration to prevent damage to the internal DMOS structures.

Selection Notes

Select this component when moderate current drive capability is required for multiple LEDs without external transistors. The integrated shift register simplifies microcontroller pin usage compared to parallel drivers. Consider thermal dissipation capabilities within the TSSOP package for high-density PCB layouts. Verify compatibility with existing SPI clock speeds and logic levels before finalizing the design.

Part Context

This part belongs to Texas Instruments' TLC6C59x family of 8-bit shift-register LED drivers. These devices are engineered to replace complex discrete driver circuits by integrating control logic and power stages into a single monolithic IC. The family offers scalable solutions for various lighting densities and voltage requirements across consumer and industrial sectors.

Replacement Considerations

Direct replacements include other members of the TLC6C59x series such as TLC6C598QDRQ1 for automotive qualified versions. Cross-reference pinouts and electrical characteristics carefully when substituting with generic 8-bit shift registers, as integrated power stages differ significantly from standard logic devices.
