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.
