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
• Fully Compatible with ISO11898−3 Standard
• Optimized for In−Car Low−speed Communication
♦ Baud Rate up to 125 kB
♦ Up to 32 Nodes can be Connected
♦ 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)
♦ Fully Integrated Receiver Filters
♦ Permanent Dominant Monitoring of Transmit Data Input
♦ Differential Receiver with Wide Common−Mode
Range for High Electromagnetic Susceptibility
(EMS) in Normal− and Low−Power Modes
♦ True 3.3 V Digital I/O Interface to CAN Controller
for AMIS−41683 Only
• Management in Case of Bus Failure
♦ In the Event of Bus Failures, Automatic Switching
to Single−Wire Mode, even when the CANH Bus
Wire is Short−Circuited to V
CC
♦
The Device will Automatically Reset to Differential
Mode if the Bus Failure is Removed
♦ During Failure Modes There is Full Wake−up
Capability
♦ Unpowered Nodes do not Disturb Bus Lines
♦ Bus Errors and Thermal Shutdown Activation is
Flagged on ERR
Pin
• Protection Issues
♦ Short Circuit Proof to Battery and Ground
♦ Thermal Protection
♦ The Bus Lines are Protected Against Transients in
an Automotive Environment
♦ An Unpowered Node Does not Disturb the
Bus Lines
• Support for Low Power Modes
♦ Low Current Sleep and Standby Mode with
Wake−up via the Bus Lines
♦ Power−on Flag on the Output
♦ Two−Edge Sensitive Wake−up Input Signal via
Pin WAKE
• I/Os
♦ The unpowered chip cannot be parasitically supplied
either from digital inputs or from digital outputs
• These are Pb−Free Devices*
