Rev. 6.0, 6/2012
Smart Front Corner Light Switch
(Triple 10 mOhm and Dual
35 mOhm)
The 10XS3535 is designed for low voltage automotive and industrial
lighting applications. Its five low R
DS(ON)
MOSFETs (three 10 mΩ, two
35 mΩ) can control the high sides of five separate resistive loads
(bulbs, Xenon-HID modules and LEDs).
Programming, control and diagnostics are accomplished using a
16-bit SPI interface (3.3 V or 5.0 V). Each output has its own pulse-
width modulation (PWM) control via the SPI. The 10XS3535 has highly
sophisticated failure mode handling to provide high availability of the
outputs. Its multiphase control and output edge shaping improves
electromagnetic compatibility (EMC) behavior.
The 10XS3535 is packaged in a power-enhanced 12 x 12 mm
nonleaded PQFN package with exposed tabs.

Clock Input
This pin is the current sense recopy of the external SMART MOSFET.
This input wakes the device. It also controls the Outputs 1 and 2 in case of Fail
mode activation. This pin has a passive internal pull-down.
This input wakes the device. It is also used to initialize the device configuration
and fault registers through SPI. This digital pin has a passive internal pull-down.
This input wakes the device. This pin has a passive internal pull-down.
This pin state depends on RST logic level.
As long as RST input pin is set to logic [0], this pin is pulled up in order to report
wake event. Otherwise, the PWM frequency and timing are generated from this
digital clock input by the PWM module.
This pin has a passive internal pull-down.
The Fail mode can be activated by this digital input. This pin has a passive
internal pull-down.
This input wakes the device. This pin has a passive internal pull-down.
When this digital signal is high, SPI signals are ignored. Asserting this pin low
starts a SPI transaction. The transaction is signaled as completed when this
signal returns high. This pin has a passive internal pull-up resistance.
This digital input pin is connected to the master microcontroller providing the
required bit shift clock for SPI communication. This pin has a passive internal
pull-down resistance.

Definition
This data input is sampled on the positive edge of the SCLK. This pin has a
passive internal pull-down resistance.
SPI Logic power supply.
SPI data is sent to the MCU by this pin. This data output changes on the
negative edge of SCLK and when CS is high, this pin is high-impedance.
This pin controls an external SMART MOSFET by logic level. This output is also
called OUT6.
If OUT6 is not used in the application, this output pin is set to logic high when
the current sense output becomes valid when CSNS sync SPI bit is set to logic
[1].
