AMIS-41682 Datasheet, PDF (1/16 Pages) ON Semiconductor – Fault Tolerant CAN Transceiver

AMIS-41682, AMIS-41683
Fault Tolerant CAN
Transceiver
Description
The new AMIS−41682 and AMIS−41683 are interfaces between the
protocol controller and the physical wires of the bus lines in a control
area network (CAN). AMIS−41683 is identical to the AMIS−41682
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 single−wire transmitter and/or receiver. Initially it will
be used for low speed applications, up to 125 kB, in passenger cars.
Both AMIS−41682 and AMIS−41683 are implemented in I2T100
technology enabling both high−voltage analog circuitry and digital
functionality to co−exist on the same chip.
These products consolidate the expertise of ON Semiconductor for
in−car multiplex transceivers and support together with
0REMX−002−XTP (VAN), AMIS−30660 and AMIS−30663 (CAN
high speed) and AMIS−30600 (LIN) another widely used physical
layer.
