AMIS ? 30623
The circuit will return to normal mode if a valid LIN frame
is received (this valid frame can be addressed to another
slave).
Thermal Shutdown Mode
When thermal shutdown occurs, the circuit performs a
<SoftStop> command and goes to motor shutdown
mode (see Figure 14: State Diagram Temperature
Management).
Temperature Management
The AMIS ? 30623 monitors temperature by means of two
thresholds and one shutdown level, as illustrated in the state
diagram and illustration of Figure 14: State Diagram
Temperature Management below. The only condition to
reset flags <TW> and <TSD> (respectively thermal warning
and thermal shutdown) is to be at a temperature lower than
Ttw and to get the occurrence of a GetStatus or a
GetFullStatus LIN frame.
