Applications

• Automotive door lock actuators
• Window lift systems
• Seat adjustment motors
• Mirrors and wiper control

Procurement Notes

Verify the NRND (Not Recommended for New Designs) status before finalizing any procurement plans. Confirm that existing inventory or legacy supply chains can sustain long-term production requirements. Ensure compatibility with current system architectures given the component's end-of-life designation.

Selection Notes

Select this component only if the design already incorporates the L9958 family architecture. Evaluate the trade-off between the specific 2.5A to 8.6A current handling capabilities and the available SPI control interface. Consider the PowerSSO package constraints and the necessity for AEC-Q100 compliance in the target application environment.

Part Context

This part belongs to the L9958 series of motor drivers specifically engineered for automotive body electronics. It serves as a specialized solution for driving DC motors in vehicle access and comfort systems, providing a compact alternative to discrete driver implementations while ensuring high reliability under automotive operating conditions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, engineers should initiate a formal Design-In review to identify potential future obsolescence risks and begin sourcing alternative components for new designs.
