TPS922051D2DSGR

Overview

The TPS922051D2DSGR is a high-side LED driver from Texas Instruments designed for automotive applications. It integrates two independent channels capable of driving up to 3A per channel with constant current regulation. The device features an integrated bootstrap diode and supports PWM dimming via a dedicated input pin. It operates within a wide supply voltage range and includes comprehensive protection mechanisms such as over-temperature, open-load, and short-to-ground/battery detection.

Feature Summary

• Integrates two independent high-side LED driver channels with constant current control
• Supports PWM dimming for precise brightness adjustment
• Includes built-in protection against over-temperature, open loads, and short circuits

Applications

• Automotive exterior lighting systems
• Interior ambient lighting modules
• High-intensity discharge (HID) lamp ballasts

Procurement Notes

Verify the exact suffix 'D2DSGR' matches your board layout requirements, specifically regarding the exposed pad thermal connection and pinout orientation. Confirm that the operating temperature range meets your specific environmental constraints before finalizing procurement.

Selection Notes

Select this component when dual-channel high-current LED driving is required in space-constrained automotive designs. Ensure the PCB thermal design can handle the dissipation associated with 3A per channel operation under maximum load conditions.

Part Context

This part belongs to the TPS92205x family of automotive-grade LED drivers. It is designed to replace discrete solutions by integrating power switches and control logic into a single compact package, reducing bill of materials and assembly complexity for modern vehicle lighting architectures.

Replacement Considerations

Check for direct pin-compatible alternatives within the same TI family, such as the TPS922050 or TPS922052, ensuring voltage and current ratings align with your specific circuit requirements.
