DESCRIPTION
The IC is designed for LIN slave applications. The microcontroller is
completely protected from the harsh automotive environment.
For sensor applications only these two ICs are needed. Even the
sensor supply can be done as a rule with the integrated
100mA VDD regulator.
The over temperature protection disables the voltage regulator
and the bus driver. After return to normal operation conditions a
reset function will be generated.
Two versions of this IC with different reset levels are available:
E910.18: 3.15V / 4.65V and E910.45: 3.15V / 3.95V
