MC40XS6500CEK

Overview

The MC40XS6500CEK is a high-side power distribution switch IC from NXP Semiconductors, designed for automotive applications. It features six independent output channels with a maximum on-resistance of 40 mOhms. The device operates within a supply voltage range of 7 V to 18 V and supports an output current of up to 5.5 A per channel. It is housed in a SOIC-EP-32 surface-mount package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Six-channel high-side switching capability with low on-resistance for efficient power distribution
• Integrated protection mechanisms including overcurrent and thermal shutdown
• Status flag output for real-time fault monitoring and system diagnostics

Applications

• Automotive lighting control systems
• Power distribution units (PDUs) in vehicles
• High-current load switching in automotive electronics

Procurement Notes

Verify the specific suffix 'CEK' against official NXP documentation to confirm pinout and electrical characteristics, as suffixes define package and tape/reel specifications. Confirm end-of-life status and obsolescence notices prior to procurement, as this component may be subject to discontinuation. Ensure compatibility with existing PCB footprints and thermal management requirements for the SOIC-EP-32 package.

Selection Notes

Select this component when a multi-channel high-side switch with robust automotive-grade reliability is required. The 40 mOhm on-resistance offers a balance between conduction loss and cost compared to lower resistance alternatives. Consider the 7V-18V operating range suitability for standard 12V automotive electrical systems. Evaluate the need for integrated status flags if diagnostic feedback is critical to the application design.

Part Context

This part belongs to the MC12XS6 series of high-side switches from NXP Semiconductors. These devices are engineered for automotive environments, providing scalable power distribution solutions. The series typically includes variants with different on-resistances and voltage ratings to suit various load requirements while maintaining consistent interface and protection features.

Replacement Considerations

Check for direct substitutes within the MC12XS6 family or newer generations from NXP. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Note that the MC40XS6500DEK is a related variant with similar characteristics but potentially different packaging or sourcing qualifications.
