MC17XS6500CEK

Overview

The MC17XS6500CEK is a Penta 17 mOhm High-side Switch from NXP Semiconductors, designed for automotive lighting drivers. It features five independent high-side switches with a typical on-resistance of 17 milliohms. The device operates within an input voltage range of 7.0 to 18 V, with extended mode support up to 28 V. Control is managed via a 16-bit SPI interface operating at 5.0 MHz. Key electrical parameters include a sleep current of less than 5.0 μA and compatibility with -16V reverse polarity conditions.

Feature Summary

• Integrates five high-side switches with dynamic overcurrent threshold profiling to manage inrush currents while maintaining load tracking.
• Supports output edge shaping to improve electromagnetic performance during switching transitions.
• Features a Fail operation mode that maintains operational control and protection when external microcontroller communication is lost.
• Provides programmable current sensing ratios and battery voltage feedback through the SPI interface.

Applications

• Automotive incandescent lamp control
• Light-emitting diode (LED) driver circuits
• Electronic Control Unit (ECU) power distribution

Procurement Notes

Verify the specific suffix 'CEK' against official NXP documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact variant required for your PCB footprint and thermal management design. Cross-reference datasheet revision levels to confirm feature compatibility before finalizing procurement orders.

Selection Notes

Select this component for applications requiring precise current monitoring and robust fault protection in automotive environments. The integrated SPI interface allows for flexible configuration of PWM duty cycles and diagnostic reporting. Consider the exposed pad package for thermal dissipation requirements associated with high-current loads.
