AMIS-42665
High-Speed Low Power
CAN Transceiver
Description
The AMIS42665 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and may be used in both 12 V and 24 V systems. The transceiver
provides differential transmit capability to the bus and differential
receive capability to the CAN controller.
Due to the wide commonmode voltage range of the receiver inputs,
the AMIS42665 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.
The AMIS42665 is a new addition to the CAN highspeed
transceiver family and offers the following additional features:
Features
Wakeup (WU) Over Bus
Voltage Source via VSPLIT Pin for Stabilizing the Recessive Bus
Level (Further EMC Improvement)
Ideal Passive Behavior when Supply Voltage is Removed
Extremely Low Current Standby Mode
Compatible with the ISO 11898 Standard (ISO 118982, ISO
118985 and SAE J2284)
High Speed (up to 1 Mbps)
Ideally Suited for 12 V and 24 V Industrial and Automotive
Applications
Extremely Low Current Standby Mode with Wakeup via the Bus
www.DataSLheoewt4UE.McoEmCommonMode Choke is No Longer Required
Differential Receiver with Wide CommonMode Range ($35 V) for
High EMS
Transmit Data (TxD) Dominant Timeout Function
Thermal Protection
Bus Pins Protected against Transients in an Automotive Environment
Power Down Mode in which the Transmitter is Disabled
Bus and VSPLIT Pins Short Circuit Proof to Supply Voltage and
Ground
Logic Level Inputs Compatible with 3.3 V Devices
These are PbFree Devices
