TLC6C5912PWR

Overview

The TLC6C5912PWR is a monolithic, medium-voltage, low-current power 12-bit shift register designed for systems requiring moderate load power. It features twelve power DMOS transistor outputs capable of delivering 50 mA continuous current per channel. The device operates with a wide VCC range from 3 V to 5.5 V and supports an output maximum rating of 40 V. It includes thermal shutdown protection and functions as a linear shift register dimming driver in a 20-TSSOP package.

Feature Summary

• Twelve power DMOS transistor outputs providing 50 mA continuous current capability
• Wide supply voltage range supporting operation from 3 V to 5.5 V
• Integrated thermal shutdown protection for enhanced reliability
• Monolithic design optimized for moderate load power applications

Applications

• Automotive LED lighting systems
• General-purpose LED display drivers
• Medium-voltage LED string driving circuits
• Low-current power logic interfaces

Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package variant when sourcing. Confirm AEC-Q100 qualification status if automotive compliance is required, noting that qualified variants may carry distinct suffixes such as 'Q'. Ensure input documentation matches the exact part number to avoid confusion with non-automotive or different package versions within the same family.

Selection Notes

Select this component for designs requiring a 12-channel shift register with direct high-side drive capabilities. It is suitable for applications needing moderate current levels up to 50 mA per output without external transistors. Consider the 40 V output rating for series LED configurations. Evaluate thermal management requirements given the integrated protection features and package constraints.

Part Context

This part belongs to the TLC6C5912 series of 12-channel shift-register LED drivers. It serves as a power interface between low-voltage logic controllers and higher-voltage LED loads. The PWR suffix specifically denotes the plastic small-outline wrapper (TSSOP) package type, distinguishing it from other form factors like SOIC available in the same functional family.

Replacement Considerations

Direct substitutes include the TLC6C5912QDWRQ1, which offers the same functionality in an SOIC-20 package with automotive qualification. Non-qualified equivalents exist under the base model name TLC6C5912, though package and temperature range specifications must be verified for compatibility.
