PACKAGE

ÿ LIN transceiver with voltage regulator

E910.18 | E910.45

FEATURES

–24V to +30V (independent of VS)

current limitation

and two reset levels:

E910.18: 3.15V and 4.65V

E910.45: 3.15V and 3.95V

at typ. 7.3V

APPLICATION

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
