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 R_DS(ON) channels (<10 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.
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, 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.
