FUNCTIONAL DESCRIPTION
The L9615 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
μ
s to prevent de-
struction of the IC and high consumption of
supply current I
S
. If V
C_L
>V
C_Lmax
the transmitter
output stages would be disabled immediately.
Pin ASC makes it possible to select two different
modes of operation: High speed (
≤
500kBaud) and
low speed (
≤
125kBaud).
The ASC pin is tied to GND for normal operation
at
≤
500kBaud. For slower speed operation at
≤
125kBaud the rise and fall slope of the bus out-
put can be decreased to reduce EMI by connect-
ingg the ASC pin to V
S
.
