AMIS ? 30621
Thermal Shutdown Mode
When thermal shutdown occurs, the circuit performs a
< SoftStop> command and goes to motor shutdown mode
(see Figure 14).
Temperature Management
The AMIS ? 30621 monitors temperature by means of two
thresholds and one shutdown level, as illustrated in the state
diagram and illustration of Figure 14 below. The only
condition to reset flags <TW> and <TSD> (respectively
thermal warning and thermal shutdown) is to be at a
temperature lower than T tw and to get the occurrence of a
GetStatus or a GetFullStatus LIN frame.
T ° > Ttw
T ° < Ttw
Normal Temp. Thermal warning
? < Tinfo > = “00” ? < Tinfo > = “ 10 ”
? < TW > = ‘0’ ? < TW > = ‘ 1 ’
? < TSD > = ‘0’ ? < TSD > = ‘0’
T ° < Ttw &
LIN frame: T ° > Ttw
GetStatus or
GetFullStatus
T ° > Ttsd
Thermal shutdown
? < Tinfo > = “ 11 ”
? < TW > = ‘1’
? < TSD > = ‘ 1 ’
? SoftStop if
motion ongoing
? Motor shutdown
(motion disabled)
Post thermal
warning
T ° > Ttsd
T ° < Ttsd
T ° < Ttw
T ° < Tlow
T ° > Tlow
Low Temp.
? < Tinfo > = “ 01 ”
? < TW > = ‘0’
? < TSD > = ‘0’
? < Tinfo > = “ 00 ”
? < TW > = ‘1’
? < TSD > = ‘0’
Post thermal
shutdown 2
? < Tinfo > = “ 00 ”
? < TW > = ‘1’
? < TSD > = ‘1’
? Motor shutdown
(motion disabled)
Post thermal
shutdown 1
? < Tinfo > = “ 10 ”
? < TW > = ‘1’
? < TSD > = ‘1’
? Motor shutdown
(motion disabled)
