Dual 16 mOhmHigh Side Switch
The 16XSD200 device is part of a 36 V dual high side switch product
family with integrated control, and a high number of protective and
diagnostic functions. It has been designed for industrial applications.
The low R_DS(ON) channels (<16 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. 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
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.
