Short Description
This IC is a fully integrated LIN Slave for matrix switch or single switch Applications in automotive environment. It is
suitable for bus systems according to LIN 2.x as well as SAE J2602.
The combination of physical layer LIN transceiver and LIN protocol controller along with easy to configure switch
inputs and PWM outputs make it possible to develop in a short timeframe simple, but powerful and cheap switch
slave nodes for LIN Bus systems.

[1] Parameter not tested in production, guaranteed by qualification.
[2] Switch parameter not determined by the IC, values are calculation basis for all currents and thresholds
[3] The current is determined by the master pull-up. To prevent discharging of the battery, the master pull up will be disconnected
under Loss of Ground conditions
[4] Resistance is valid for the sum of switch resistance and the ESD protection resistance
[5] A 500Ohm series resistor is required in case of the remote switch outside of the module and the switch is in this case directly
supplied from the battery
