Overview
The MC50XS4200DEK is a dual high-side switch from NXP Semiconductors, designed for truck and bus applications. It features two fully protected channels with low on-resistance (50 mΩ at 25 °C) capable of handling up to 1.65 A steady-state current per channel. The device integrates control logic and diagnostic functions accessible via a 16-bit SPI interface. Powered by SMARTMOS technology, it supports individual channel control through internal or external clock signals, enabling autonomous operation. Key protections include overcurrent, short-circuit, and overtemperature detection with programmable autoretry.
Feature Summary
- Dual high-side switches with integrated diagnostics and protection
- SPI-controlled configuration and monitoring capabilities
- Autonomous operation support via programmable internal clocks
- Dynamic overcurrent threshold profiling for inrush current management
Applications
- Truck electrical systems
- Bus load control applications
- Bulb and solenoid switching
- DC motor control
Procurement Notes
Verify the specific suffix 'DEK' against official NXP documentation to confirm package type and tape/reel specifications. Confirm end-of-life status as related variants may be discontinued. Ensure compatibility with existing PCB footprints and SPI communication protocols before integration.
Selection Notes
Select this component for applications requiring robust high-side switching with integrated fault protection. The dual-channel design simplifies board layout for controlling multiple loads like bulbs or motors. Verify that the 16-bit SPI interface aligns with the host microcontroller's available peripherals and voltage levels.
Part Context
This part belongs to the MC50XS4200 family of 24 V dual high-side switches. These devices are engineered for automotive environments, specifically heavy-duty vehicles. The family emphasizes reliability through SMARTMOS technology and comprehensive diagnostic feedback via serial interfaces.
Replacement Considerations
Check for direct pin-to-pin replacements within the MC50XS series. Verify if alternative suffixes (e.g., BEK) offer identical electrical characteristics and packaging. Consult NXP for current production status of similar dual high-side switch models.
