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.
Warning:
The application should limit the number of consecutive GetStatus or GetFullStatus 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.
Notes:
(0) The Priority Encoder is describing the management of states and commands. The note below is to be considered illustrative.
(1) If the LIN communication is lost while in shutdown mode, the circuit enters the sleep mode immediately.
15.0 Lin Controller
15.1 General Description
The local interconnect network (LIN) is a serial communications protocol that efficiently supports the control of mechatronic nodes in
distributed automotive applications. The interface implemented in the AMIS-30621 is compliant with the LIN rev. 1.3 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-wire communication
Transmission speed of 19.2kbit/s
Selectable length of message frame: 2, 4 and 8 bytes
Configuration flexibility
Data checksum 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.
