Two versions of this IC with different reset levels are available:
E910.18:
3.15V
/
4.65V
and E910.45:
3.15V
/
3.95V
The over temperature protection disables the voltage regulator
and the bus driver. After return to normal operation conditions a
reset function will be generated.
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.
DESCRIPTION
The IC is designed for LIN slave applications. The microcontroller is
completely protected from the harsh automotive environment.
