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 125kBaud, 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 multiples 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.
