Power Distribution Switches, Load Drivers Procurement Notes

This specific part number is officially listed as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on remaining stock or authorized distributors rather than new production runs. Engineers must confirm the exact suffix compatibility if substituting with similar family members, as ordering codes define specific package and tape/reel configurations. Always consult the latest official discontinuation notices for accurate lifecycle status.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when dual-channel high-side switching with integrated diagnostics is required for 12V or 24V systems. The through-hole package suits prototyping or applications where board space allows larger footprints. Ensure the load current does not exceed 3.5 A per channel and that the ambient temperature remains within the specified -30°C to +85°C range for reliable long-term operation.

Power Distribution Switches, Load Drivers Part Context
