AMIS-42700 Dual High-Speed CAN Transceiver
1.0 Key Features
Preimnary Data Shee
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 12V and 24V
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.
2.0 Key Features
Fully compatible with the ISO 11898-2 standard
Certified “Authentication on CAN Transceiver Conformance (d1.1)”
High speed (up to 1 Mbit/s)
Ideally suited for 12V and 24V industrial and automotive applications
Low EME common-mode-choke is no longer required
Differential receiver with wide common-mode range (+/- 35V) for high EMS
No disturbance of the bus lines with an un-powered node
Transmit data (TxD) dominant time-out function
Thermal protection
Bus pins protected against transients in an automotive environment
Power down mode in which the transmitter is disabled
Short circuit proof to supply voltage and ground
Logic level inputs compatible with 3.3V devices
ESD protection guaranteed up to
±
8KV
