MC07XSF517EK

Overview

The MC07XSF517EK is a dual high-side switch device from the Freescale Semiconductor family, designed for low-voltage lighting and factory automation applications. It integrates two low RDS(ON) MOSFETs with a maximum resistance of 7.0 mΩ at 25°C. The component operates within a voltage range of 6.0 to 20 V, supporting an extended mode from 4.0 to 28 V, while maintaining a sleep current below 5.0 µA. Control and status reporting are handled via an 8.0 MHz 16-bit SPI interface with daisy-chain capability. The device features a PWM module using an external clock or calibratable internal oscillator, along with programmable output delay management. Protection mechanisms include smart overcurrent shutdown compliant with huge inrush currents, severe short-circuit conditions, and over-temperature events, featuring time-limited auto-retry and fail-safe modes. Output diagnostics cover open-load detection for bulbs or LEDs and short-to-battery detection, supplemented by analog current feedback with selectable ratios and board temperature feedback.

Applications

• Low-voltage automotive lighting systems
• Factory automation load control
• Xenon module driving
• LED array management
• DC low voltage motor control

Procurement Notes

Verify the exact suffix EK indicates the specific evaluation kit or packaging variant as defined by the manufacturer's documentation. Confirm that the component source aligns with NXP Semiconductors, following the acquisition of Freescale. Ensure technical specifications match the official datasheet for the MC07XSF517EK part number before integration into design files.

Selection Notes

Select this component when dual independent high-side switching is required for loads such as lamps, LEDs, or small motors. The integrated diagnostic features simplify system monitoring compared to discrete solutions. Consider the operating voltage range and thermal requirements relative to the expected load current and ambient conditions. The SPI interface suitability should be evaluated against the host microcontroller's available communication peripherals.

Part Context

This device belongs to the 07XSC series of dual high-side switches originally developed by Freescale Semiconductor. Following the merger announced in late 2015, these products are now managed under NXP Semiconductors. The series is characterized by its robust protection features and diagnostic capabilities, targeting automotive and industrial markets where reliability and fault detection are critical for system safety and maintenance.
