MC10XS4200BFK

Overview

The MC10XS4200BFK is a dual high-side switch from NXP Semiconductors, designed for truck, bus, and industrial applications. It features two fully protected channels with low on-resistance of less than 10 mΩ at 25 °C, capable of controlling bulbs, solenoids, or DC motors. Each channel supports up to 8.5 A steady-state current. The device integrates control and diagnostic functions accessible via a 16-bit serial peripheral interface (SPI). Powered by SMARTMOS technology, it includes programmable output voltage slew rates for EMC improvement and dynamic overcurrent threshold profiles to manage inrush currents while tracking load current.

Feature Summary

• Dual high-side switches with integrated control and extensive protective functions
• Low RDS(ON) channels suitable for various load types including bulbs and DC motors
• Programmable internal or external PWM clock signals for autonomous operation
• Dynamic overcurrent threshold profile to handle inrush currents without shutdown

Applications

• Truck electrical systems
• Bus electrical systems
• Industrial equipment control

Procurement Notes

Verify the specific suffix BFK against official documentation to confirm package type and tape/reel specifications. Confirm end-of-life status as some variants are discontinued. Ensure compatibility with existing SPI interfaces and voltage levels. Check for moisture sensitivity classification requirements during storage and handling.

Selection Notes

Select this component when designing systems requiring dual high-side switching with precise current sensing and diagnostic capabilities. The integrated SPI interface simplifies integration with microcontrollers. Consider the programmable slew rates for electromagnetic compatibility needs. Verify that the 8.5 A per channel rating meets the load requirements for bulbs, solenoids, or DC motors in the target application.
