FUNCTIONAL DEVICE OPERATION
Supply and VBAT Block
VBAT Monitoring—VBAT is the main power supply coming
from the battery voltage after an external protection diode
(for reverse battery). VBAT is monitored for under voltage
and over voltage.
VBAT Under Voltage—VBAT is monitored for under voltage
if it is below 4.0 V the BatFail flag is set in the VSSR
register and a maskable interrupt is sent to the
microcontroller.
VBAT Over Voltage— When VBAT is > 20 V, the BatHigh
flag is set in the VSSR register. A maskable interrupt is
sent to the microcontroller. No specific action is taken to
reduce current consumption (to limit power dissipation).
This is to allow the entire flexibility to the microcontroller for
a decision.
CAN Transceiver
The device incorporates a low speed 125 kBaud CAN
physical interface. Its electrical parameters for the CANL,
CANH, RTL,RTH, RX, and TX pins are identical to the 33388,
stand alone CAN physical interface.
The mode control for the CAN transceiver (Normal, VBAT
Stand-by, Sleep, etc.) are selectable through the 33389 SPI
interface.
Baud Rate up to 125 kBit/s
Supports unshielded bus wires
Short-circuit proof to battery and ground in 12 V powered
systems
Supports single-wire transmission modes with ground
offset voltages up to 1.5 V
Automatic switching to single wire mode in case of bus
failures
Automatic reset to differential mode if bus failure is
removed
Low Electromagnetic Interference (EMI) due to built-in
slope control and signal symmetry
Fully integrated receiver filters
Thermally protected
Bus lines protected against automotive transients
Low current Bus Stand-by mode with wake-up capability
via the bus
An unpowered node does not disturb the bus lines

CONSEQUENCE OF FAILURE DETECTIONS
S1 is the switch from RTH to Ground
S2 is the switch from RTL to V2 and
S3 is the switch from RTL to VBAT
Each failure type provides data concerning which switch is
open and which driver is disabled.
Failure 1: Nothing done
Failure 2: Nothing done
Failure3: S1 open. Driver CANH is disabled
Failure4: S2 and S3 open. Driver CANL is disabled
Failure5: Nothing done
Failure6: S2 and S3 open. Driver CANL disabled
Failure7: S2 and S3 open. Driver CANL disabled
Failure8: S1 Open. CANH driver disable
