Overview
The MC08XS6421CEKR2 is a high-side power switch IC from NXP Semiconductors, designed for automotive lighting applications. It features a dual-channel configuration with low on-resistance values of 8 mOhms and 21 mOhms per channel. The device operates at a nominal 12 V system voltage and supports continuous load currents up to 5.5 A and 11 A respectively. Packaged in a 32-pin SOIC-EP (SOICEP) surface-mount package, it integrates protection features suitable for harsh automotive environments.
Feature Summary
- Dual-channel high-side switching architecture for independent load control
- Low on-resistance design to minimize power dissipation and heat generation
- Integrated diagnostic and protection mechanisms for robust automotive operation
- Designed specifically for driving automotive lighting loads
Applications
- Automotive exterior lighting systems
- Interior vehicle illumination circuits
- High-side load distribution in automotive ECUs
- LED driver power stages
Procurement Notes
Verify the specific suffix 'R2' indicates reel packaging when sourcing. Confirm current lifecycle status as obsolete or limited availability through authorized distributors. Ensure compatibility with existing PCB footprints for the 32-SOIC-EP package. Check for alternative sources if original manufacturing has ceased.
Selection Notes
Select this component for applications requiring dual high-side switches with distinct current handling capabilities. Compare on-resistance values against thermal management requirements. Ensure the 12V operating range matches the target vehicle electrical system. Verify that the SOICEP 32 package fits the mechanical constraints of the design.
Part Context
This part belongs to the MC08XS6421 series of high-side switches. It shares functional similarities with evaluation kits like KIT08XS6421EKEVB but is intended for final production integration rather than development. The series targets automotive lighting drivers requiring reliable power distribution.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. The component lifecycle status is listed as obsolete. Engineers should consult NXP Semiconductors directly for recommended next-generation replacements or cross-reference compatible devices from other manufacturers.
