Fault Tolerant CAN
Transceiver
Description
The new AMIS41682 and AMIS41683 are interfaces between the
protocol controller and the physical wires of the bus lines in a control
area network (CAN). AMIS41683 is identical to the AMIS41682
but has a true 3.3 V digital interface to the CAN controller. The device
provides differential transmit capability but will switch in error
conditions to a singlewire transmitter and/or receiver. Initially it will
be used for low speed applications, up to 125 kB, in passenger cars.
Both AMIS41682 and AMIS41683 are implemented in I2T100
technology enabling both highvoltage analog circuitry and digital
functionality to coexist on the same chip.
These products consolidate the expertise of ON Semiconductor for
incar multiplex transceivers and support together with
0REMX002XTP (VAN), AMIS30660 and AMIS30663 (CAN
high speed) and AMIS30600 (LIN) another widely used physical
layer.
