MC40XS6500EKR2

Overview

The MC40XS6500EKR2 is a high-side power switch IC from NXP Semiconductors, designed for automotive load distribution. It features six independent output channels with a maximum on-resistance of 40 milliohms. The device operates within a supply voltage range of 7 to 18 volts and supports a control logic voltage of 4.5 to 5.5 volts. It is housed in a 32-pin HSOP package with exposed pad for thermal management. The component is qualified to AEC-Q100 standards and functions reliably across an extended temperature range from -40°C to +125°C ambient temperature.

Feature Summary

• Six-channel high-side switching capability with integrated PWM functionality
• Comprehensive fault protection including over-temperature, short-circuit, and open-load detection
• Serial Peripheral Interface (SPI) communication for configuration and diagnostic monitoring

Applications

• Automotive lighting systems requiring high-current distribution
• General purpose load switching in vehicle electronic control units
• Power distribution networks in automotive infotainment architectures

Procurement Notes

Verify the exact suffix 'EKR2' against official NXP documentation to confirm tape-and-reel packaging specifications. Confirm that the part number corresponds to the 40-milliohm variant rather than other resistance options within the family. Check current lifecycle status as distribution channels may list obsolete or end-of-life inventory. Ensure compatibility with existing PCB footprints and thermal design requirements before finalizing procurement.

Selection Notes

Select this component when six isolated high-side outputs are required with low on-resistance for efficient power delivery. The SPI interface allows for precise control and real-time diagnostics, making it suitable for complex automotive networks. Consider the 40-milliohm on-resistance value for applications balancing conduction losses with cost. Verify that the operating voltage range aligns with the specific vehicle's electrical system architecture and load requirements.

Part Context

This part belongs to the MC17XS/MC40XS series of high-side switches from NXP Semiconductors. These devices are engineered for robust automotive applications, offering integrated protection and diagnostic features. The series provides scalable solutions for power distribution, differing primarily in on-resistance values and specific feature sets. The MC40XS6500 variant specifically targets applications requiring moderate current handling with advanced fault management capabilities.
