TPS929240QDCPRQ1

LED Driver IC Overview

The TPS929240QDCPRQ1 is a 24-channel automotive LED driver IC featuring high-side outputs with up to 100 mA current per channel. It supports input voltages from 4.5 V to 40 V and operates within a temperature range of -40°C to +125°C. The device utilizes a FlexWire interface with clock frequencies up to 1 MHz for communication. It provides 12-bit independent PWM dimming with programmable frequencies up to 20 kHz, alongside linear and exponential dimming methods. The package is a 38-HTSSOP.

LED Driver IC Feature Summary

• Supports 24 precision high-side current outputs with less than ±5% accuracy across the operating range.
• Features a FlexWire control interface compatible with CAN physical layer for robust long-distance communication.
• Includes comprehensive diagnostic capabilities such as open LED detection, ground short circuit protection, and single LED short diagnosis.

LED Driver IC Applications

• Automotive exterior lighting systems requiring individual pixel control
• Matrix LED headlamps integrated with ADAS sensors
• Long-range non-board communication in distributed lighting architectures

LED Driver IC Procurement Notes

Verify that the specific suffix QDCPRQ1 matches the required HTSSOP-38 package and AEC-Q100 Grade 1 qualification. Confirm that the FlexWire interface requirements align with the system's MCU capabilities. Ensure thermal management solutions accommodate the 125°C maximum junction temperature rating during operation.

LED Driver IC Selection Notes

Select this component when designing complex automotive lighting systems requiring extensive channel counts and precise current regulation. The 24-channel configuration allows for flexible matrix designs without excessive component count. Consider the 100 mA output capability for driving various optical structures and the built-in diagnostics for safety-critical applications.

LED Driver IC Part Context

This device belongs to the TPS929240-Q1 series, designed specifically for next-generation automotive lighting. It complements other variants like the TPS929160-Q1 and TPS929120-Q1 by offering a higher channel count. The series shares compatible communication protocols, allowing designers to scale channel density while maintaining system consistency.

LED Driver IC Replacement Considerations

The TPS929160QDCPRQ1 serves as a verified substitute with 16 channels. Both devices share the same 38-pin HTSSOP package and FlexWire interface compatibility, ensuring pin-to-pin interchangeability for designs requiring reduced channel counts.
