AMIS41682/D
AMIS-41682, AMIS-41683
Fault Tolerant CAN
Transceiver
Description
The new AMIS41682 and AMIS41683 are interfaces between the
protocol controller and the physical wires of the bus lines in a control
area network (CAN). AMIS41683 is identical to the AMIS41682
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 singlewire transmitter and/or receiver. Initially it will
be used for low speed applications, up to 125 kB, in passenger cars.
Both AMIS41682 and AMIS41683 are implemented in I2T100
technology enabling both highvoltage analog circuitry and digital
functionality to coexist on the same chip.
These products consolidate the expertise of ON Semiconductor for
incar multiplex transceivers and support together with
0REMX002XTP (VAN), AMIS30660 and AMIS30663 (CAN
high speed) and AMIS30600 (LIN) another widely used physical
layer.
Features
Fully Compatible with ISO118983 Standard
Optimized for InCar Lowspeed Communication
Baud Rate up to 125 kB
Up to 32 Nodes can be Connected
Due to Builtin 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 CommonMode
Range for High Electromagnetic Susceptibility
(EMS) in Normal and LowPower Modes
True 3.3 V Digital I/O Interface to CAN Controller
for AMIS41683 Only
Management in Case of Bus Failure
In the Event of Bus Failures, Automatic Switching
to SingleWire Mode, even when the CANH Bus
Wire is ShortCircuited to VCC
The Device will Automatically Reset to Differential
Mode if the Bus Failure is Removed
During Failure Modes There is Full Wakeup
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
Wakeup via the Bus Lines
Poweron Flag on the Output
TwoEdge Sensitive Wakeup Input Signal via
Pin WAKE
I/Os
The unpowered chip cannot be parasitically supplied
either from digital inputs or from digital outputs
These are PbFree Devices*
