Procurement Notes
This component is officially listed as obsolete and is no longer manufactured by STMicroelectronics. Availability is restricted to existing stock or secondary market sources. Verification of authenticity and storage history is critical due to the end-of-life status. Buyers should confirm the specific tape-and-reel packaging details and ensure compliance with humidity sensitivity handling requirements before integration into new designs.
Selection Notes
Engineers requiring this specific dual half-bridge topology must account for its discontinued status. Selection should prioritize verified surplus suppliers offering traceable documentation. Alternative modern equivalents from the same manufacturer family should be evaluated for pin compatibility and electrical parameter alignment to ensure seamless replacement without redesigning the PCB layout or control logic.
Part Context
The VN771KTR-E belongs to STMicroelectronics' portfolio of automotive interface ICs, specifically targeting motor and motion control segments. As a dual half-bridge driver, it enables bidirectional current flow for motor direction control. The 28-SO package provides thermal performance suitable for embedded automotive environments, though its obsolescence limits long-term supply chain stability for production units.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Users should consult official STMicroelectronics documentation for current active series replacements that match the dual half-bridge functional requirement.
