Dual 24 V, 20 mOhm high-side switch The 20XS4200 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 has been designed for truck, bus, and industrial applications. The low RDS(on) channels (<20 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 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.
