The LIN-SBC is a fully integrated LIN transceiver, complying with the LIN specification, and with
a low-drop voltage regulator for 5V/50 mA output and a window watchdog adjustable via an
external resistor. The voltage regulator is able to source 50 mA at V
temperature of 105°C. The output current of the regulator can be boosted by using an external
NPN transistor. This combination makes it possible to develop simple, but powerful and cheap,
slave nodes in LIN bus systems. LIN-SBC is designed to handle the low speed data communica-
tion in vehicles, for example, in convenience electronics. Improved slope control at the LIN driver
ensures secure data communication up to 20 kBaud. The bus output is capable of withstanding
60V. Sleep mode and Silent mode guarantee a very low current consumption.
