TLC6C5712QPWPRQ1

Overview

The TLC6C5712QPWPRQ1 is an automotive-grade LED driver IC featuring 12 constant-current sink channels. It supports PWM dimming with a resolution of up to 12 bits per channel and includes full diagnostic capabilities for open-load and short-to-ground detection. The device operates within a supply voltage range of 3 V to 5.5 V, delivering up to 75 mA output current per channel. It utilizes a boost topology with an internal switch and functions at frequencies up to 8 MHz. The component is housed in a 28-HTSSOP package and is qualified to AEC-Q100 standards for operation between -40°C and +125°C.

Feature Summary

• Provides 12 independent constant-current sink channels with integrated diagnostics
• Supports high-resolution PWM dimming control up to 12 bits per channel
• Features internal boost converter topology for efficient LED driving
• Includes comprehensive fault detection for open loads and short circuits

Applications

• Automotive exterior lighting systems
• Interior ambient illumination modules
• LED matrix backlighting applications
• High-precision automotive display drivers

Procurement Notes

Verify the specific suffix 'PWPRQ1' corresponds to the HTSSOP-28 package and reel packaging configuration. Confirm that the Q1 designation aligns with AEC-Q100 Grade 1 requirements for your target temperature range. Ensure input voltage levels remain within the specified 3 V to 5.5 V limits during system integration. Cross-reference the datasheet revision date to confirm compatibility with existing design specifications.

Selection Notes

Select this component when 12-channel precision control is required alongside robust diagnostic feedback. The 75 mA output capability suits standard automotive LED arrays. Consider the 12-bit resolution for smooth dimming transitions in sensitive lighting environments. Evaluate the HTSSOP-28 footprint against available PCB space constraints. Verify thermal management needs given the 125°C maximum operating temperature rating.

Part Context

This part belongs to the TLC6C571x family of automotive LED drivers from Texas Instruments. It shares architectural similarities with other members like the TLC6C5716 but offers fewer channels. The series is designed specifically for demanding automotive environments requiring high reliability and detailed fault reporting. It complements broader lighting control solutions by providing dedicated driver functionality.

Replacement Considerations

The TLC6C5716QPWPRQ1 serves as a direct substitute offering 16 channels instead of 12, maintaining similar diagnostic features and package type. Designers must account for pinout compatibility and software configuration differences when migrating between these variants. No other cross-model replacements are confirmed in public documentation.
