AMIS-41682, AMIS-41683
Fault Tolerant CAN
Transceiver
Description
The new AMISâ41682 and AMISâ41683 are interfaces between the
protocol controller and the physical wires of the bus lines in a control
area network (CAN). AMISâ41683 is identical to the AMISâ41682
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 singleâwire transmitter and/or receiver. Initially it will
be used for low speed applications, up to 125 kB, in passenger cars.
Both AMISâ41682 and AMISâ41683 are implemented in I2T100
technology enabling both highâvoltage analog circuitry and digital
functionality to coâexist on the same chip.
These products consolidate the expertise of ON Semiconductor for
inâcar multiplex transceivers and support together with
0REMXâ002âXTP (VAN), AMISâ30660 and AMISâ30663 (CAN
high speed) and AMISâ30600 (LIN) another widely used physical
layer.
