High Speed CAN Interface with

Embedded 5.0 V Supply

The MC33902 is a high speed CAN physical interface. The device

includes an internal 5.0 V supply for the CAN bus transceiver, and

requires only a connection to a battery line.

The MC33902 provides 4 operation modes, including low power

modes with remote and local wake-up.

The device has very low sleep and standby current consumption.

Features

• High speed CAN interface for baud rates of 40 kb/s to 1.0 Mb/s

• Compatible to ISO11898 standard

• Single supply from battery. No need for a 5.0 V supply for CAN

interface

• I/O compatible from 2.75 V to 5.5 V via a dedicated input terminal

(3.3 V or 5.0 V logic compatible)

• Low Power mode with remote CAN wake-up and local wake-up

recognition and reporting

• CAN bus failure diagnostics and TXD/RXD pin monitoring, cold

start detection, wake-up sources reported through the ERR pin

• Enhanced diagnostics for bus, TXD, RXD and supply pins

available through Pseudo SPI via existing terminals EN, STBY

and ERR.

• Split terminal for bus recessive level stabilization

• INH output to control external voltage regulator

• Pb-free packaging designated by suffix code EF
