Analog, Mixed-Signal and Power Management MC06XS4200 Dual 24 V, 6.0 mOhm High Side Switch Overview Applications The MC06XS4200 device is part of a 24 V high side switch product family with integrated control, and a high number of protective and diagnostic functions. It is designed for truck, bus, and industrial applications. The low RDS(ON) channels (<6.0 mΩ) can control different load types; bulb lamps, 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. Both channels can be controlled individually by external or internal clock signals, or by direct inputs. Using the internal clock allows fully autonomous device operation. Programmable output voltage slew-rates (individually programmable) help improve electromagnetic compatibility (EMC) performance. To avoid shutting off the device due to inrush current, while still being able to closely track the load current, a dynamic over-current 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.
