MC50XS4200DEK

Power Distribution Switches, Load Drivers 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.
