AMIS 30660 D

AMIS-30660
High Speed CAN
Transceiver
Description
The AMIS−30660 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and may be used in both 12 V and 24 V systems. The transceiver
provides differential transmit capability to the bus and differential
receive capability to the CAN controller.
Due to the wide common−mode voltage range of the receiver inputs,
the AMIS−30660 is able to reach outstanding levels of
electromagnetic susceptibility (EMS). Similarly, extremely low
electromagnetic emission (EME) is achieved by the excellent
matching of the output signals.

FUNCTIONAL DESCRIPTION

The behavior of AMIS−30660 under various conditions is
illustrated in Table 5 below. In case the device is powered,
one of two operating modes can be selected through Pin S.

High−Speed Mode
circuit is particularly necessary when a bus line
short−circuits.
If Pin S is pulled low (or left floating), the transceiver is
in its high−speed mode and is able to communicate via the
bus lines. The signals are transmitted and received to the
CAN controller via the Pins TxD and RxD. The slopes on the
bus line outputs are optimized to give extremely low
electromagnetic emissions.
TxD Dominant Time−out Function
A TxD dominant time−out timer circuit prevents the bus
lines from being driven to a permanent dominant state
(blocking all network communication) if Pin TxD is forced
permanently low by a hardware and/or software application
failure. The timer is triggered by a negative edge on pin TxD.
If the duration of the low−level on Pin TxD exceeds the
internal timer value tdom, the transmitter is disabled, driving
the bus into a recessive state. The timer is reset by a positive
edge on Pin TxD.
Silent Mode
In silent mode, the transmitter is disabled. All other IC
functions continue to operate. The silent mode is selected by
connecting Pin S to VCC and can be used to prevent network
communication from being blocked, due to a CAN
controller which is out of control.
Fail−Safe Features
Overtemperature Detection
A current−limiting circuit protects the transmitter output
stage from damage caused by an accidental short−circuit to
either positive or negative supply voltage, although power
dissipation increases during this fault condition.
The Pins CANH and CANL are protected from
automotive electrical transients (according to “ISO 7637”;
see Figure 3). Pin TxD is pulled high internally should the
input become disconnected.
A thermal protection circuit protects the IC from damage
by switching off the transmitter if the junction temperature
exceeds a value of approximately 160°C. Because the
transmitter dissipates most of the power, the power
dissipation and temperature of the IC is reduced. All other
IC functions continue to operate. The transmitter off−state
resets when Pin TxD goes high. The thermal protection

is flowing out of the pin.
All voltages are referenced to GND (Pin 2). Positive
currents flow into the IC. Sinking current means the current
