Dual 16 mOhmHigh 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.

Definition
This pin either outputs a current proportional to the channel’s output current or
a voltage proportional to the temperature of the GND pin (pin 14). Selection
between current and temperature sensing, as well as setting the current
sensing sensitivity are performed through the SPI interface. An external pull-
down resistor must be connected between CSNS and GND.
The IN[0 : 1] input pins are used to directly control the switching state of both
switches and consequently the voltage on the HS0 : HS1 output pins. The pins
are connected to GND by internal pull-down resistors
FSOB is asserted (active-low) upon entering Fail-safe mode (see
Functional
Description)
This open-drain output requires an external pull-up resistor to
VPWR
The CONF[0 : 1] input pins are used to select the appropriate overcurrent
detection profile (bulb/DC motor) for each of both channels. CONF requires a
pull-down resistor to GND.
This open-drain output pin (external pull-up resistor to VDD required) is set
when the device enters Fault mode (see
Fault Mode)
The clock input gives the time-base when the device is operated in external
clock/internal PWM mode.
This pin has an internal pull-down current source.

Reset
This input pin is used to initialize the device’s configuration - and fault registers.
Reset puts the device in Sleep mode (low current consumption) provided it is
not stimulated by direct input signals.This pin is connected to GND by an
internal pull-down resistor.
This input pin is connected to the SPI chip-select output of an external micro-
controller. CSB is internally pulled up to V

Definition
This input pin is to be connected to an external SPI Clock signal. The SCLK
pin is internally connected to a pull-down current source I
DWN
This input pin receives the SPI input data from an external device (micro-
controller or another extreme switch device in case of daisy-chaining). The SI
pin is internally connected to a pull-down current source I
DWN
This is the positive supply pin of the SPI interface.
This output pin transmits SPI data to an external device (external micro-
controller or the SI pin of the next SPI device in case of daisy-chaining). The
pin doesn’t require external pull-up or pull-down resistors, but a series resistor
is recommended to limit current consumption in case of GND disconnection
These pins, internally connected, are the ground pins for the logic - and analog
circuitry. It is recommended to also connect these pins on the PCB.

Synchronization
Output pins of the switches, to be connected to the load.
This output pin is asserted (active low) when the Current Sense (CS) output
signal is within the specified accuracy range. Reading the SYNC pin allows the
external micro-processor to synchronize to the device when operating in
autonomous operating mode. SYNC is open-drain and requires a pull-up
resistor to VDD.
