FUNCTIONAL DESCRIPTION
The L9616 is used as an interface between a
CAN controller and the physical bus. The device
provides transmitting capability to the CAN con-
troller.
The transmitter outputs C_H and C_L are pro-
tected against short circuits and electrical tran-
sients which may occur in an automotive environ-
ment. In case of short circuit (C_H to C_L, C_H to
B) the protection circuit recognizes this fault con-
ditionand the transmitter output stages are dis-
abled with a delay of max. 10 s to prevent de-
struction of the IC and high consumption of
supply current I
output stages would be disabled immediately.
Pin ASC makes it possible to select two different
