Network” Physical Interface
MC33399
The MC33399 is a Physical Layer component dedicated to automotive sub
bus applications. The device is compliant to LIN specification. Its main
features are:
• Speed Communication from 1 to 20Kb/s
• Nominal Operation from VSUP 8 to 18V DC
• Fully Functional up to 27V DC battery voltage.
• 40V maximum Voltage during Load Dump
• Handle from +40V to -18V DC voltage at LIN pin
• Gnd disconnection fail safe at module level
• An Unpowered Node does not disturb the network
• GND Shift Operation at system level
• Two Operation Modes: Normal and Sleep Mode
• Very Low Standby Current during Sleep Mode 20uA
• Wake-up Capability from LIN bus, MCU command and dedicated high
voltage wake up input (interface to external switch)
• Interface to MCU with CMOS compatible I/O pins
• Control of External Voltage Regulator
• LIN bus Threshold Voltage fully Compatible with LIN protocol specification
• Bus slew rate control according to LIN protocol specification
recommendations (2V/us typ.)
• Internal pull up resistor
• Handle Automotive Transients per ISO9137 Specification
• ESD 4KV on LIN bus Pin
• High EMC Immunity
