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