Power Supply Controllers, Monitors Procurement Notes

Verify component status carefully as this part is listed as obsolete. Confirm availability through authorized distributors or secondary markets, noting potential lead times and minimum order quantities. Ensure the specific 48-TQFP-EP package matches your PCB footprint requirements. Cross-reference datasheets for any pin-compatible alternatives if direct sourcing is unavailable.

Power Supply Controllers, Monitors Selection Notes

Select this component only if the application requires a hybrid controller compatible with the 9V to 15V input range. The 48-TQFP-EP package necessitates specific thermal management considerations due to the exposed pad. Verify that the 20mA supply current fits the system's power budget. Consider the obsolete status when planning long-term production cycles.

Power Supply Controllers, Monitors Part Context

The L6740LTR belongs to STMicroelectronics' portfolio of switch controllers and hybrid controllers. It is distinct from their MCU lines like STM32 or other regulators such as LDOs. The component serves specialized power control functions rather than general-purpose computing or simple voltage regulation, fitting into niche industrial or automotive power architectures.

Power Supply Controllers, Monitors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, alternative solutions must be evaluated based on functional equivalence and package compatibility.
