Dual 24 V, 10 mOhm High Side
Switch
10XS4200
The 10XS4200 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 (<10 m) can control different
load types; bulbs, solenoids, or DC motors. Control, device
HIGH SIDE SWITCH
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 or 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
compatability (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.
