General Description

The TH8065 consists of a low-drop voltage regulator 5V/70mA combined with a Reset/Watchdog unit and a LIN bus transceiver. The LIN transceiver is suitable for LIN bus systems conform to LIN specification revision 2.0 and SAE J2602.

The combination of voltage regulator and bus transceiver makes it possible to develop simple, but powerful and cheap slave nodes in LIN Bus systems.
