Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix QTR indicates the tape and reel packaging configuration when ordering. Confirm the 48-VFQFPN package dimensions match the target PCB footprint. Ensure the design accounts for the thermal requirements associated with the VFQFPN 7x7 package under maximum load conditions. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring a dual full bridge driver with integrated logic and power stages. The BCD technology allows for compact system design by combining power and control functions. Consider the 5.6A peak current capability and 0.3Ω on-resistance for efficiency calculations. The diagnostic output facilitates robust fault management in critical motor control systems.

Full Half-Bridge (H Bridge) Drivers Part Context

The L6206QTR belongs to the L6206 family of dual full bridge drivers from STMicroelectronics. While other variants like L6206D utilize SOIC packages, the QTR variant specifically employs the 48-VFQFPN package for higher density surface mount applications. This family is characterized by its ability to drive inductive loads such as motors and solenoids with integrated protection features.

Full Half-Bridge (H Bridge) Drivers Replacement Considerations

Direct pin-to-pin replacements within the same package are limited. The L6206D013TR offers similar electrical characteristics but uses a 24-SO package, requiring layout changes. Verify functional equivalence regarding overcurrent detection methods and diagnostic signal polarity before substituting.
