LIN System basis chip  
System Basis Chip with  
LIN transceiver  
SILICON MONOLITHIC  
INTEGRATED CIRCUIT  
The LIN SBC is a monolithic integrated circuit combining many functions  
frequently used by automotive LIN distributed slave nodes. It incorporates:  
- Single voltage regulator with low power modes  
- LIN physical interface.  
- Wake up inputs.  
- Triple high side driver  
- Current sense op amp  
Pin out SO32WB fine pitch  
• Vdd: Low drop voltage regulator, current limitation, over temperature  
detection, monitoring and reset function, current capability 50mA.  
• Programmable window watchdog  
• Three operational modes (normal, stop and sleep modes)  
• Low current consumption in sleep and stop modes  
• LIN physical interface compatible with LIN standard.  
• Two external high voltage wake-up inputs  
• Dual high side switches, relay driver capability, internal clamp, PWM  
capability.  
• Single low current high side switch, 50mA capability for switch bias and hall
