Description

The MCP201 provides a physical interface between amicrocontroller and a LIN half-duplex bus. It is intendedfor automotive and industrial applications with serialbus speeds up to 20 Kbaud. It provides a half-duplex, bidirectional communications interface between a microcontroller and the serial network bus. This MCP201 will translate the CMOS/TTL logic levels to LIN level logic, and vice versa. The regulator MCP201 has been specificallydesigned to operate in the automotive environmentand will survive reverse battery connections,+40V load dump transients and double-battery jumps.
