Power Management - Specialized Procurement Notes

Verify the component status carefully, as public records indicate this specific part number may be obsolete. Confirm availability through authorized distributors or secondary market suppliers. Ensure the 8-SOIC package dimensions match your PCB footprint requirements. Validate that the 9V-16.5V input range aligns with your vehicle's power bus specifications before integration.

Power Management - Specialized Selection Notes

Select this component when designing for dedicated wipe/wash control logic in automotive platforms. It is appropriate for systems requiring integrated power management without external complex sequencing circuits. Consider the -40°C to +85°C industrial temperature rating for under-hood or exterior module placement. Evaluate alternative active parts if new production volume requires guaranteed long-term supply.
