MC33388 : CAN Low Speed Fault Tolerant Physical 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.

MC33388 Features

• Dedicated to 12 V systems
• Ambient temperature range from -40C to 125C.
• Baud rate from 10 kBaud up to 125kBaud
• Bus line short-circuit protected to battery, VDD and ground
• Thermal protection of bus line drivers
• Automatic switching to single wire mode in case of bus failures and reset to differential mode if bus failures are disappeared
• Supports one wire transmission modes with ground offset up to 1.5V
• Internal bus driver slope control function to minimize RFI
• Bus line protected against transients in an automotive environment
• Very low sleep/standby current (15mA)
• Wake-up capability from bus and dedicated wake-up pin
• Supports unshielded bus wires and up to 32 nodes
• An unpowered node does not disturb the bus lines
• Battery fail on NERR output
