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.

FUNCTIONAL DESCRIPTION

Description

AMIS−41682 is a fault tolerant CAN transceiver which

works as an interface between the CAN protocol controller

and the physical wires of the CAN bus (see Figure 2). It is

primarily intended for low speed applications, up to 125 kB,

in passenger cars. The device provides differential transmit

capability to the CAN bus and differential receive capability

to the CAN controller.

The AMIS−41683 has open−drain outputs (RXD and

ERR Pins), which allow the user to use external pullup

resistors to the required supply voltage; this can be 5 V or

3.3 V.

To reduce EME, the rise and fall slope are limited.

Together with matched CANL and CANH output stages,

this allows the use of an unshielded twisted pair or a parallel

pair of wires for the bus lines.

The failure detection logic automatically selects a suitable

transmission mode, differential or single−wire transmission.

Together with the transmission mode, the failure detector

will configure the output stages in such a way that excessive

currents are avoided and the circuit returns to normal

operation when the error is removed.

A high common−mode range for the differential receiver

guarantees reception under worst case conditions and

together with the integrated filter the circuit realizes an

excellent immunity against EMS. The receivers connected

to pins CANH and CANL have threshold voltages that

ensure a maximum noise margin in single−wire mode.

A timer has been integrated at Pin TXD. This timer

prevents the AMIS−41682 from driving the bus lines to a

permanent dominant state.

Failure Detector

The failure detector is fully active in the normal operating

mode. After the detection of a single bus failure the detector

switches to the appropriate mode. The different wiring

failures are depicted in Figure 4. The figure also indicates

the effect of the different wiring failures on the transmitter

and the receiver. The detection circuit itself is not depicted.

The differential receiver threshold voltage is typically set

at 3 V (VCC = 5 V). This ensures correct reception with a

noise margin as high as possible in the normal operating

mode and in the event of failures 1, 2, 4, and 6a. These

failures, or recovery from them, do not destroy ongoing

transmissions. During the failure, reception is still done by

the differential receiver and the transmitter stays fully

active.

To avoid false triggering by external RF influences the

single−wire modes are activated after a certain delay time.

When the bus failure disappears for another time delay, the

transceiver switches back to the differential mode. When

one of the bus failures 3, 5, 6, 6a, and 7 is detected, the

defective bus wire is disabled by switching off the affected

bus termination and the respective output stage. A wake−up

from sleep mode via the bus is possible either by way of a

dominant CANH or CANL line. This ensures that a

wake−up is possible even if one of the failures 1 to 7 occurs.

If any of the wiring failure occurs, the output signal on pin

ERR will become low. On error recovery, the output signal

on pin ERR will become high again.

During all single−wire transmissions, the EMC

performance (both immunity and emission) is worse than in

the differential mode. The integrated receiver filters

suppress any HF noise induced into the bus wires. The

cut−off frequency of these filters is a compromise between

propagation delay and HF suppression. In the single−wire

mode, LF noise cannot be distinguished from the required

signal.

Figure 4. Different Types of Wiring Failure

Low Power Modes

The transceiver provides three low power modes, which

can be entered and exited via Pins STBB and EN (see

Figure 5). (Go−to−sleep mode is only a transition mode.)

The sleep mode is the mode with the lowest power

consumption. Pin INH is switched to high−impedance for

deactivation of the external voltage regulator. Pin CANL is

biased to the battery voltage via Pin RTL. If the supply

voltage is provided, Pins RXD and ERR will signal the

wake−up interrupt signal.

The standby mode will react the same as the sleep mode

but with a high−level on pin INH.

The power−on standby mode is the same as the standby

mode with the battery power−on flag instead of the wake−up

interrupt signal on Pin ERR. The output on Pin RXD will

show the wake−up interrupt. This mode is only for reading

out the power−on flag.

Wake−up request is detected by the following events:

AMIS−41682, AMIS−41683

http://onsemi.com

•Local Wake−up: Rising or falling edge on input WAKE

(levels maintained for a certain period).

•Remote Wake−up from CAN Bus: A message with five

consecutive dominant bits.

On a wake−up request the transceiver will set the output

on Pin INH high which can be used to activate the external

supply voltage regulator. Note: Pin INH is also set similarly

as an after wake up event by VBAT voltage being below the

battery power on flag level. (See FLAG_VBAT in Figure 5)

If VCC is provided, the wake−up request can be read on the

ERR or RXD outputs so the external microcontroller can

wake−up the transceiver (switch to normal operating mode)

via Pins STB and EN.

In the low power modes the failure detection circuit

remains partly active to prevent increased power

consumption in the event of failures 3, 3a, 4, and 7.

The go−to−sleep−mode is only a transition mode. The Pin

INH stays active for a limited time. During this time the

circuit can still go to another low−power mode. After this

time the circuit goes to the sleep−mode. In case of a wake up

request (from BUS or WAKE Pin) during this transition

time, the wake−up request has higher priority than

go−to−sleep and INH will not be deactivated.

Behavior in Case of Missing Supplies

If VCC is below the threshold level FLAG_VCC, the signals

on pins STB and EN will internally be set to low-level to

provide fail safe functionality. In this way, a low-power mode

will be forced in case of missing/failing VCC supply.

Similarly, missing/failing VBAT supply – i.e. VBAT being

below FLAG_VBAT level - will lead to a fail-safe behavior of

the transceiver by forcing a low-power mode.

A forced low-power in case of missing supplies

guarantees that the transceiver will in no way disturb the

other CAN nodes when the local electronic unit looses

ground or battery connection.

Figure 5. Low Power Modes

Power−On

After power−on (VBAT switched on) the signal on Pin INH

will become high and an internal power−on flag will be set.

This flag can be read in the power−on standby mode via pin

ERR (STB = 1; EN = 0) and will be reset by entering the

normal operating mode.

Protections

A current limiting circuit protects the transmitter output

stages against short circuit to positive and negative battery

voltage. If the junction temperature exceeds a maximum

value, the transmitter output stages are disabled and flagged

on the ERR pin. Because the transmitter is responsible for

the major part of the power dissipation, this will result in

reduced power dissipation and hence a lower chip

temperature. All other parts of the IC will remain operating.

The Pins CANH and CANL are protected against

electrical transients that may occur in an automotive

environment.
