±80V Fault-Protected/Tolerant CAN
Transceivers for In-Car Applications

MODE
DESCRIPTION
Detection
Sensing a permanent dominant condition on CANH for a timeout period.
Receiver
Receiver switches to single ended on CANL.
Driver
CANH and RTH are both switched off (high impedance) and transmission continues on CANL after timeout.
Recovery
When the short is removed, the recessive bus voltage is restored. If the differential voltage remains below the
recessive threshold level for the timeout period, reception and transmission switch back to the differential mode.

Failure 3—CANH Short Circuited to Battery
MODE
DESCRIPTION
Detection
Sensing a permanent dominant condition for a timeout period.
Receiver
Receiver switches to single ended on CANH.
Driver
CANL and RTL are both switched off (high impedance) and transmission continues on CANH after timeout.
Recovery
When the short is removed, the recessive bus voltage is restored. If the differential voltage remains below the
recessive threshold level for the timeout period, reception and transmission switch back to the differential mode.
Failure 4—CANL Short Circuited to GND
MODE
DESCRIPTION
Detection
Detection is provided, sensing the pulse-count difference between CANH and CANL (pulse count = 4).
Receiver
Receiver remains in differential mode. No received data lost.
Driver
RTH remains on and CANH remains enabled.
Recovery
Recovery is provided, sensing the edge-count difference between CANH and CANL after the detection of four
consecutive pulses.
Failure 5—CANH Short Circuited to Ground or Below Ground (Normal Mode Only)
MODE
DESCRIPTION
Detection
Detected by a comparator for CANL > 7.3V after a timeout period.
Receiver
Receiver switches to single ended on CANH after timeout.
Driver
RTL is switched off after timeout. CANH remains active.
Recovery
Sensing CANL < 7.3V after the timeout period.
Failure 6—CANL Short Circuited to Battery (Normal Mode Only)
MODE
DESCRIPTION
Detection
Sensing a permanent dominant condition on the differential comparator (CANH - CANL > -3.2V) for the timeout
period.
Receiver
Receiver switches to CANH single-ended mode after timeout.
Driver
CANL and RTL are both switched off after timeout. Transmission remains ongoing on CANH.
Recovery
When the short is removed, the recessive bus voltage is restored (RTL on if CANH - CANL < -3.2V) but CANL still
remains disabled and ERR = 0. If the differential voltage remains below the recessive threshold level (CANH -
CANL < -3.2V) for the timeout period, reception and transmission switch back to the differential mode.
Failure 7—CANL Mutually Short Circuited to CANH
