MC10XS4200BDFKR2

Overview

The MC10XS4200BDFKR2 is a dual high-side switch from NXP Semiconductors, utilizing SMARTMOS technology for automotive and industrial applications. It features two channels with low on-resistance of less than 10 mΩ at 25 °C, supporting steady-state currents up to 8.5 A per channel. The device integrates comprehensive protection mechanisms including overcurrent, short-circuit, and overtemperature safeguards with programmable autoretry functions. Configuration and diagnostics are managed via a 16-bit serial peripheral interface (SPI). It supports individual control through external or internal clock signals, enabling autonomous operation and enhanced electromagnetic compatibility through programmable slew rates.

Feature Summary

• Dual high-side switches with integrated diagnostic and protective functions
• Low on-resistance channels suitable for bulbs, solenoids, and DC motors
• Programmable internal or external PWM clock signals for autonomous operation
• Dynamic overcurrent threshold profile to manage inrush current while tracking load

Applications

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

Procurement Notes

Verify the specific suffix BDFKR2 against official NXP documentation to confirm package type and tape/reel specifications. Confirm component status as active or last-time-buy before design finalization. Ensure environmental compliance data matches project requirements. Cross-reference pinout details with the official datasheet to prevent integration errors during PCB layout.

Selection Notes

Select this component for applications requiring robust high-side switching with integrated diagnostics. The SPI interface allows flexible configuration of protection thresholds and operating modes. Consider the thermal performance and current handling capabilities relative to the specific load types. Evaluate the need for autonomous operation features provided by the internal clock functionality.
