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 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.

Definition
1
CSNS
Output
Output Current/ This pin either outputs a current proportional to the channel’s output current or
Temperature
a voltage proportional to the temperature of the GND pin (pin 14). Selection
Monitoring
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.
2
IN0 Input
Direct Inputs
The IN[0:1] input pins are used to directly control the switching state of both
3 IN1
switches and consequently the voltage on the HS0:HS1 output pins. The pins
are connected to GND by internal pull-down resistors
4
FSOB
Output
Fail-safe Output FSOB is asserted (active-low) upon entering Fail-safe mode (see Functional
(Active Low)
Description) This open-drain output requires an external pull-up resistor to
VPWR
5
CONF0
Input
Configuration Input The CONF[0:1] input pins are used to select the appropriate over-current
6 CONF1
detection profile (bulb /DC motor) for each of both channels. CONF requires a
pull-down resistor to GND.

8
CLOCK
Input
Fault Status
(Active Low)
PWM Clock
This open-drain output pin (external pull-up resistor to VDD is 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.
9
RSTB
Input
Reset
This input pin is used to initialize the device’s configuration - and fault registers.
Reset will put 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.
10
CSB
Input
Chip Select
(Active Low)
This input pin is connected to the SPI chip-select output of an external micro-
controller. CSB is internally pulled up to VDD by a current source IUP.
