NXP Semiconductors Document Number: MC50XSD200 Rev. 2.0, 8/2016 Data Sheet: Advance Information Dual 24 V, 50 mOhm high-side switch 50XSD200 The 50XSD200 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 industrial applications. The low R channels (<50 m) can DS(on) control different load types bulbs, solenoids, or DC motors. Control, device configuration, and diagnostics are performed through a 16-bit serial peripheral HIGH-SIDE SWITCH 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 compatibility (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 communication with the external microcontroller is lost, the device enters a Fail-safe operation mode, but remains operational, controllable, and protected.
