Important : While in shutdown mode, since there is no hold
current in the coils, the mechanical load can cause a step loss,
which indeed cannot be flagged by the AMIS ? 30621.
If the LIN communication is lost while in shutdown mode,
the circuit enters the sleep mode immediately (Note 1).
Warning : The application should limit the number of
commands to try to get the AMIS ? 30621 out of shutdown
mode when this proves to be unsuccessful, e.g. there is a
permanent defect. The reliability of the circuit could be
altered since Get(Full)Status attempts to disable the
protection of the H ? bridges.
Note 1 : The Priority Encoder is describing the management

of states and commands.
LIN CONTROLLER
General Description
The LIN (local interconnect network) is a serial
communications protocol that efficiently supports the
control of mechatronics nodes in distributed automotive
applications. The physical interface implemented in the
AMIS ? 30621 is compliant to the LIN rev. 2.0 & 2.1
specifications. It features a slave node, thus allowing for:
? single ? master / multiple ? slave communication
? self synchronization without quartz or ceramics
resonator in the slave nodes
? guaranteed latency times for signal transmission
? single ? signal ? wire communication
? transmission speed of 19.2 kbit/s
? selectable length of Message Frame: 2, 4, and 8 bytes
? configuration flexibility
? data checksum (classic checksum, cf. LIN1.3) security
and error detection
? detection of defective nodes in the network
It includes the analog physical layer and the digital
protocol handler.
The analog circuitry implements a low side driver with a
pull ? up resistor as a transmitter, and a resistive divider with
a comparator as a receiver. The specification of the line
driver/receiver follows the ISO 9141 standard with some
enhancements regarding the EMI behavior.
