Driver Output Protection
Thermal Shutdown
If the junction temperature exceeds +165°C, the driver is
switched off. Thermal hysteresis is 15°C, disabling ther-
mal shutdown once the temperature reaches +150°C.
Overcurrent Protection
A current-limiting circuit protects the transmitter output
stage against a short circuit to a positive and negative
battery voltage. Although the power dissipation increases
during this fault condition, this feature prevents destruc-
tion of the transmitter output stage.
Failure Management
The failure detector is fully active in normal operating
mode. After the detection of a single failure, the detec-
tor switches to the appropriate state (see Table 1).
The differential receiver threshold voltage is set to -3.2V
typically (VCC = 5V). This ensures correct reception
with a noise margin as high as possible in the normal
operating mode and in the event of failures 1, 2, 5, and 9.
If any of the wiring failures occur, the output signal on
pin ERR becomes LOW after detection. On error recov-
ery, the output signal on pin ERR becomes HIGH.

MODE
DESCRIPTION
Detection
The external termination resistance connected to the RTH pin provides an instantaneous pulldown of the open
CANH line to GND. Detection is provided, sensing the pulse-count difference between CANH and CANL (pulse
count = 4).
Receiver
The receiver remains in differential mode. No received data lost.
Driver
Driver remains in differential mode. No transmission data lost.
Recovery
Recovery is provided sensing the pulse-count difference between CANH and CANL after the detection of four
consecutive pulses.
