The LIN-SBC is a fully integrated LIN transceiver, which complies with the LIN 2.0, 2.1 and
SAEJ2602-2 specifications. It has a low-drop voltage regulator with a 5V/50mA output and a
window watchdog.
The LIN-SBC is designed to handle the low-speed data communication in vehicles, e.g., in
convenience electronics. Improved slope control at the LIN-driver ensures secure data com-
munication up to 20kBaud. Sleep Mode and Silent Mode guarantee very low current
consumption.
Master and Slave Operation Possible
Supply Voltage up to 40V
Operating voltage V
Typically 10µA Supply Current During Sleep Mode
Typically 57µA Supply Current in Silent Mode
Linear Low-drop Voltage Regulator:
VCC Undervoltage Detection (4ms 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, 2.1 Specification and SAEJ2602-2
Wake-up Capability via LIN-bus, Wake Pin, or Kl_15 Pin
INH Output to Control an External Voltage Regulator or to Switch off the Master Pull-up
Resistor
TXD Time-out Timer
Bus Pin is Overtemperature and Short-circuit Protected versus GND and Battery
Adjustable Watchdog Time via External Resistor
