AMIS−41682/D

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.

Features
