Overview: NXP Semiconductors Data Sheet: Technical data Document Number: MC50XS4200 Rev. 7.0, 9/2022 Dual 24 V, 50 mOhm high-side switch
The 50XS4200 device is part of a 24 V dual high-side switch product family with integrated control, and a high number of protective and diagnostic functions. It is designed for truck and bus applications. The low RDS(on) channels (<50 mΩ) can control different load types; bulbs, solenoids, or DC motors. Control, device configuration, and diagnostics are performed through a 16-bit serial peripheral interface (SPI), allowing easy integration into existing applications. This device is powered by SMARTMOS technology.
Both channels can be controlled individually by external/internal clock signals, or by direct inputs. Using the internal clock allows fully autonomous device operation. Programmable output voltage slew rates (individually programmable) helps improve electromagnetic patibility (EMC) performance. To avoid shutting off the device upon inrush current, while still being able to closely track the load current, a dynamic overcurrent threshold profile is featured. Switching current of each channel can be sensed with a programmable sensing ratio. Whenever munication with the external microcontroller is lost, the device enters a Fail-safe operation mode, but remains operational, controllable, and protected.
