MC50XS4200CEK

Overview

The MC50XS4200CEK is a dual high-side switch from NXP Semiconductors, designed for truck and bus applications. It features two fully protected channels with low RDS(on) of less than 50 mΩ at 25 °C, capable of controlling bulbs, solenoids, or DC motors. The device supports up to 1.65 A steady-state current per channel and includes integrated control via a 16-bit SPI interface. Key protective functions include overcurrent, short-circuit, and overtemperature protection with programmable autoretry. It utilizes SMARTMOS technology and offers dynamic overcurrent threshold profiling to handle inrush currents while tracking load current accurately.

Feature Summary
