MC17XS6500EEKR2

Overview

The MC17XS6500EEKR2 is a high-side switch IC from NXP Semiconductors designed for automotive lighting applications. It features six independent outputs with a maximum on-resistance of 17 mOhms and supports an output current of 5.5 A per channel. The device operates within a supply voltage range of 4.5 V to 5.5 V and withstands load voltages between 7 V and 18 V. It utilizes a 32-pin SOICEP package (SOICEP-32) suitable for surface mount installation. The component functions across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates five channels with dynamic overcurrent threshold profiling to manage inrush currents while maintaining precise load tracking capabilities.
• Features SPI interface control for programmable PWM duty cycles, open load detection, and thermal shutdown prewarning mechanisms.
• Includes fail-safe operation modes that maintain protection and controllability even during external microcontroller communication loss.

Applications

• Automotive LED headlight modules
• Incandescent lamp drivers
• Electronic Control Unit (ECU) power distribution

Procurement Notes

Verify the specific suffix EK indicates lead-free status as per manufacturer documentation. Confirm the 32-HSOP/SOICEP-32 package dimensions match your PCB footprint requirements. Check moisture sensitivity level (MSL 3) handling procedures before assembly. Ensure the 1000-unit reel packaging aligns with your production volume needs.

Selection Notes

Select this component when designing systems requiring six-channel high-side switching with low on-resistance for efficient power distribution. Consider the integrated diagnostic features such as open load detection and thermal protection for robust automotive environments. Evaluate the SPI interface compatibility with your existing microcontroller architecture for seamless integration.
