Procurement Notes
This part number is classified as obsolete and is no longer manufactured by onsemi. Distributors may offer limited remaining stock or refurbished units, but availability is not guaranteed. Verification of authenticity and lot date codes is critical when sourcing from secondary markets. Designers should prioritize replacement components with active status to ensure long-term supply chain stability and consistent quality assurance.
Selection Notes
Engineers selecting this component must account for its obsolete status and potential supply constraints. The specific voltage ranges and current capabilities define its suitability for low-power BLDC applications. Alternative selection should focus on modern equivalents that maintain similar pinout compatibility and electrical characteristics while offering active manufacturing support and updated reliability data.
Part Context
The LB11620T-TLM-E belongs to onsemi's legacy line of motor drivers and controllers. It represents an earlier generation of integrated solutions for three-phase brushless motors. The product family focuses on providing compact, cost-effective drive stages for consumer and industrial electronics. Its design reflects historical requirements for integrated protection and control functions in small form factor packages.
Replacement Considerations
DigiKey lists available substitutes for this obsolete component. Engineers should evaluate these alternatives based on electrical parameter matching and mechanical footprint compatibility. Official onsemi documentation should be consulted to identify recommended cross-references that ensure functional equivalence in existing designs.
