FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
Sleep and Stop Mode
In Sleep and Stop modes the high sides are disabled.
High Side Output HS3
This high side switch can be used to drive small lamps,
Hall-effect sensors, or switch pull-up resistors. Control is
done using the SPI Control register. No direct PWM control is
possible on this pin (refer to Figure 14, page 22).
Current Limit (Over-current) Protection
This high side feature switch feature current limit to protect
it against over-current and short-circuit conditions.
Over-temperature Protection
If an over-temperature condition occurs on any of the three
high side switches, all high side switches (HS1, HS2, and
HS3) are turned off and latched off. The failure is reported by
the HSST bit in the SPI Control register.
Sleep and Stop Mode
In Sleep and Stop mode the high side is disabled.

LIN PHYSICAL LAYER
The LIN bus pin provides a physical layer for single-wire
communication in automotive applications. The LIN physical
layer is designed to meet the LIN physical layer specification.
The LIN driver is a low side MOSFET with over-current
protection and thermal shutdown. An internal pull-up resistor
with a serial diode structure is integrated, so no external
pullup components are required for the application in a slave
node. The fall time from dominant to recessive and the rise
time from recessive to dominant is controlled. The symmetry
between both slew rate controls is guaranteed.
The slew rate can be selected for optimized operation at
10 and 20 kBit/s as well as a fast baud rate for test and
programming. The slew rate can be adapted with the bits
LINSL2:1 in the SPI Control Register. The initial slew rate is
optimized for 20 kBit/s.
