AMIS−42700
Controller area network (CAN) is a serial communication protocol,
which supports distributed real−time control and multiplexing with
high safety level. Typical applications of CAN−based networks can be
found in automotive and industrial environments.
The AMIS−42700 Dual−CAN transceiver is the interface between
up to two physical bus lines and the protocol controller and will be
used for serial data interchange between different electronic units at
more than one bus line. It can be used for both 12 V and 24 V systems.
The circuit consists of following blocks:
• Two differential line transmitters
• Two differential line receivers
• Interface to the CAN protocol handler
• Interface to expand the number of CAN busses
• Logic block including repeater function and the feedback suppression
• Thermal shutdown circuit (TSD)
• Short to battery treatment circuit
Due to the wide common−mode voltage range of the receiver inputs,
the AMIS−42700 is able to reach outstanding levels of
electromagnetic susceptibility (EMS). Similarly, extremely low
electromagnetic emission (EME) is achieved by the excellent
matching of the output signals.
