The LIN-SBC is a fully integrated LIN transceiver, which complies with the LIN 2.0 and
SAEJ2602-2 specifications. It has a low-drop voltage regulator with a 5V/50 mA output and a
window watchdog.
The LIN-SBC is designed to handle the low-speed data communication in vehicles, e.g., in con-
venience electronics. Improved slope control at the LIN-driver ensures secure data
communication up to 20 kBaud. Sleep Mode and Silent Mode guarantee very low current
consumption.
Master and Slave Operation Possible
Supply Voltage up to 40V
Operating voltage V
Typically 10 µA Supply Current During Sleep Mode
Typically 57 µA Supply Current in Silent Mode
Linear Low-drop Voltage Regulator:
VCC- Undervoltage Detection (4 ms Reset Time) and Watchdog Reset Logical Combined at Open
Drain Output NRES
Negative Trigger Input for Watchdog
Boosting the Voltage Regulator Possible with an External NPN Transistor
LIN Physical Layer According to LIN 2.0 Specification and SAEJ2602-2
Wake-up Capability via LIN-bus, Wake Pin, or Kl_15 Pin
