Features

of CAN are not required. This device is powered by SMARTMOS technology. The 33399 is a physical layer component dedicated to automotive sub-bus applications. It offers communication speed from 1.0 kbps to 20 kbps, and up to 60 kbps for programming mode. It has two operating modes: Normal and Sleep. The 33399 supports LIN protocol specification 1.3. Features
• Nominal operation from VSUP 7.0 to 18 V DC, functional up to 27 V DC battery voltage and capable of handling 40 V during load dump
• Active bus waveshaping to minimize radiated emission
• ±5.0 kV ESD on LIN Bus Pin, ±4.0 kV ESD on other p.
