5.7 CAN BUS TRANSCEIVER
5.7.1 Introduction
The CAN bus transceiver allows the connection of
the microcontroller, with CAN controller unit, to a
CAN bus. The transmitter section drives the CAN
bus while the receiver section senses the data on
the bus.
The CAN transceiver meets ISO/DIS 11898 up to
1 MBaud.
5.7.2 Main Features
TRANSMITTER:
– Generation of differential Output signals
– Short Circuit protection from transients in auto-
motive environment
– Slope control to reduce RFI and EMI
– High speed (up to 1Mbaud)
– If un-powered, L9805 CAN node does not disturb
the bus lines (the transceiver is in recessive
state).
RECEIVER:
– Differential input with high interference suppres-
sion
– Common mode input voltage range (V
COM
) from
-5 to 12V
5.7.3 Functional Description
The Can Bus Transceiver is used as an interface
between a CAN controller and the physical bus.
The device provides transmitting capability to the
CAN controller. The transceiver has one logic in-
put pin (TX), one logic output pin (RX) and two In-
put/Output pins for the electrical connections to
the two bus wires (CAN_L and CAN_H). The mi-
crocontroller sends data to the TX pin and it re-
ceives data from the RX pin. The transmission
slew-rates of CAN_H and CAN_L voltage are con-
trolled to reduce RFI and EMI. The transceiver is
protected against short circuit or overcurrent: If
I
CANH
and/or I
CANL
exceeds a current thresholds
I
SC
, then the CAN_H and CAN_L power transis-
tors are switched off and the transmission is disa-
bled for T

s typical.
5.7.4 CAN Transceiver Disabling function
The transceiver can be disabled and forced to
move in a low power consumption mode, setting
CANDS bit in DCSR register (see
Section 3.2.1
).
When the transceiver is in this mode it can not re-
ceive nor transmit any information to the bus. The
only way to have again on board the CAN capabil-
ities is reset CANDS bit. The CAN protocol handler
can not disable nor enable the transceiver and
there is no way to communicate to the controller
the transceiver is down. The disabling function has
the only purpose to allow the reduction of the cur-
rent consumption of the device in application not
using the CAN at all or using it for particular func-
tions (such like debugging). Current consumption
reduction, when disabling the trasceiver, can be as
high as 15mA.
Note
When the CAN capabilities of L9805 are not
needed additional consumption reduction can be
achieved putting the CAN controller in Stand-by
Mode (see
Section 5.6.3.3
).
