Single Chip LIN Slave Controller

This IC is a full integrated LIN Slave for matrix switch or single switch applications in automotive environment. It is suitable for LIN bus systems conform to “LIN protocol specification” Rev 1.3. The combination of physical layer LIN transceiver and LIN protocol controller in combination with switch matrix inputs and PWM outputs makes it possible to develop simple, but powerful and cheap switch slave nodes in LIN Bus systems.

Features
- LIN-Protocol Controller based upon the LIN protocol specification 1.3
- LIN-Transceiver based on the LIN protocol specification 1.3
- 17 Switch inputs for switch matrix up to 5 x 5 or single switches and encoder reading
- Three high current PWM outputs up to 50 mA with configurable PWM frequency and
   slew rate limitation, constant current source mode 2 to 30mA
- LIN to SPI gateway via software possible
- 3 ADC channels, one with high voltage option
- Very low standby current, 10uA in sleep mode
- Wake up by LIN traffic or up to 6 local sources
- Operating voltage VSUP = 7 to 18V
- 12 MHz internal RC-Oscillator (Tolerance < ±15% long term; < ±2% short term)
- EEPROM with internal chargepump
- Overtemperature shutdown
- Watchdog
- Direct powered from 12V boardnet with low voltage detection
- 40V load dump protected
- Small MLPQ 28 pin package, body size 6 x 6mm
