MC10XS4200FK

Overview

The MC10XS4200FK 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 10 mΩ at 25 °C. Each channel supports up to 8.5 A steady-state current. The device utilizes SMARTMOS technology and includes integrated control via a 16-bit SPI interface. Key protective functions include overcurrent, short-circuit, and overtemperature protection with programmable autoretry. It also offers accurate temperature and current sensing, open-load detection, and individually programmable output voltage slew rates to enhance electromagnetic compatibility.

Feature Summary

• Dual high-side switches with 10 mΩ on-resistance per channel
• Integrated 16-bit serial peripheral interface (SPI) for control and diagnostics
• Programmable internal or external PWM clock signals for autonomous operation
• Dynamic overcurrent threshold profile to manage inrush currents while tracking load

Applications

• Truck electrical systems
• Bus vehicle power distribution
• Industrial load control

Procurement Notes

Verify the specific suffix 'FK' against the official datasheet to confirm package type and marking details. Confirm end-of-life status and availability through authorized distributors.
