Advance Information

Fault Tolerant CAN Interface

The MC33388 is a CAN physical interface device, dedicated to automotive body electronic multiplexing applications. It operates in differential mode, allowing ground shifts up to 1,5V, reducing RFI disturbances. It offers very low standby current in sleep and standby mode operation and supports communication speeds up to 125kBauds. It is fully protected against harsh automotive environments and the driver is able to detect fault conditions and automatically switches into appropriate default mode. Under fault condition, it continuously monitors bus failures in order to switch back to normal bus operation as soon as faults disappeared.

?Very low sleep/standby current (15mA typical)

?Baud rate from 10 kBaud up to 125kBauds

?Automatic switching to single wire mode in case of bus failures and

return to differential mode if bus failures disappear

?Supports one wire transmission modes with ground offset up to 1.5V

?Internal bus driver slope control function to minimize RFI

?Bus line short-circuit protected to battery, VDD and ground

?Bus line protected against automotive transients

?Thermal protection of bus line drivers

?Supports unshielded twisted pair bus

?An unpowered node does not disturb the bus lines

?Wake-up capability triggered from bus message and wake-up input pin

?Wake up pin with dual edges sensitivity

?Battery fail flag reported on NERR output

?Ambient temperature range from -40°C to 125°C.
