Dual 24 V, 6.0 mOhm High Side
Switch
06XS4200
The 06XS4200 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 (<6.0 m) 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.
HIGH SIDE SWITCH
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) help improve EMC performance. To
avoid shutting off the device during 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.
