TPS92612QDBVRQ1

LED Driver IC Overview

The TPS92612QDBVRQ1 is an automotive single-channel LED driver IC designed for high-side switching applications. It delivers a regulated output current of up to 150 mA with integrated short-circuit protection. The device operates within an input voltage range of 4.5 V to 40 V and supports PWM dimming for brightness control. It is housed in a compact SOT-23-5 package and functions reliably across an extended temperature range from -40°C to +125°C, ensuring compliance with automotive environmental standards.

LED Driver IC Feature Summary

• Integrated short-circuit protection for enhanced system reliability
• Supports pulse-width modulation (PWM) dimming for precise brightness control
• Automotive-grade qualification for harsh operating environments

LED Driver IC Applications

• Automotive exterior lighting systems
• Interior ambient illumination circuits
• High-side LED load driving

LED Driver IC Procurement Notes

Verify the specific suffix QDBVRQ1 against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with automotive supply voltage profiles and thermal management requirements before integration. Cross-reference the component marking code with official identification guides to prevent counterfeit substitution during assembly.

LED Driver IC Selection Notes

Select this component when a single-channel, high-side LED driver with integrated protection is required. It is suitable for designs needing 150 mA constant current drive in space-constrained PCB layouts. Consider the SOT-23-5 package size and automotive temperature rating as primary selection criteria over general-purpose industrial drivers.

LED Driver IC Part Context

This part belongs to the Texas Instruments TPS926xx automotive LED driver family. It shares functional similarities with other members like the TPS92622 but differs in channel count and package configuration. The series is engineered specifically for automotive lighting applications requiring robust fault protection and efficient power management.

LED Driver IC Replacement Considerations

The TPS92622QDRRRQ1 is a dual-channel variant within the same family. Verify if single-channel operation is sufficient or if dual-channel capability is needed. Package differences between SOT-23-5 and WSON-12 require PCB layout adjustments.
