AMIS-4168X Datasheet | AMI SEMICONDUCTOR

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 3.3V 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 125k Baud, 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 AMIS for in-car multiplex transceivers and support together with AMIS-30522 (VAN), AMIS-30660 and AMIS-30663 (CAN High Speed) and AMIS-30600 (LIN) another widely used physical layer. 2.0 Key Features - Fully patible with ISO11898-3 standard - Optimized for in-car low-speed munication o Baud rate up to 125k Baud o Up to 32 nodes can be connected o Due to built-in slope control function and a very good matching of the CANL and CANH bus outputs, this device realizes a very low electromagnetic emission (EME) o Fully integrated receiver filters o Permanent dominant monitoring of transmit data input o Differential receiver with wide mon-mode range for high electromagnetic susceptibility (EMS) in normal- and low-power modes o True 3.3V digital I/O interface to CAN controller for AMIS-41683 only - Management in case of bus failure o In the event of bus failures, automatic switching to single-wire mode, even when the CANH bus wire is short circuited to VCC o The device will automatically reset to differential mode if the bus failure is removed o During failure modes there is full wake-up capability. o Un-powered nodes do not disturb bus lines o Bus errors and thermal shutdown activation is flagged on ERRB pin - Protection issues o Short circuit proof to battery and ground .. o...
