30600
The single−wire transceiver AMIS−30600 is a monolithic integrated
circuit in a SOIC−8 package. It works as an interface between the
protocol controller and the physical bus.
The AMIS−30600 is especially suitable to drive the bus line in LIN
systems in automotive and industrial applications. Further it can be
used in standard ISO9141 systems.
In order to reduce the current consumption the AMIS−30600 offers
a stand−by mode. A wake−up caused by a message on the bus pulls the
INH−output high until the device is switched to normal operation
mode.
The transceiver is implemented in I2T100 technology enabling both
high−voltage analog circuitry and digital functionality to co−exist on
the same chip.
The AMIS−30600 provides an ultra−safe solution to today’s
automotive in−vehicle networking (IVN) requirements by providing
unlimited short circuit protection in the event of a fault condition.

Figure 3. State Diagrams
The AMIS−30600 has a slope which depends of the
supply Vbat. This implementation guarantees biggest
slope−time under all load conditions. The rising slope has to
be slower then the external RC−time−constant, otherwise
the slope will be terminated by the RC−time−constant and no
longer by the internal slope−control. This would affect the
symmetry of the bus−signal and would limit the maximum
allowed bus−speed.
A capacitor of 10 mF at the supply voltage input VB
buffers the input voltage. In combination with the required
reverse polarity diode this prevents the device from
detecting power down conditions in case of negative
transients on the supply line.
In order to reduce the current consumption, the
AMIS−30600 offers a sleep operation mode. This mode is
selected by switching the enable input EN low (see Figure 4).
An external voltage regulator can be controlled via the
INH output in order to minimize the current consumption of
the whole application in sleep mode (see Figure 2). A
wake−up caused by a message on the communication bus
automatically enables the voltage regulator by switching the
INH output high (see Figure 3). In case the voltage regulator
control input is not connected to the INH output, or the
microcontroller is active respectively, the AMIS−30600 can
be set in normal operation mode by EN = H (see Figure 3).
