AMIS-30623 LIN Microstepping Motordriver
Data Sheet
15.2.4. Sleep Mode
When entering sleep mode, the stepper-motor can be driven to its secure position. After which, the circuit is completely powered down,
apart from the LIN receiver, which remains active to detect dominant state on the bus. In case sleep mode is entered while a motion is
ongoing, a transition will occur towards secure position as described in Positioning and Motion Control provided SecPos is enabled.
Otherwise, SoftStop is performed.
Sleep mode can be entered in the following cases:
The circuit receives a LIN frame with identifier 0x3C and first data byte containing 0x00, as required by LIN specification
rev 1.3. See Sleep
In case the SleepEn bit =1 and the LIN bus remains inactive (or is lost) during more than 25000 time slots (1.30s at 19.2kbit/s),
a time-out signal switches the circuit to sleep mode. See also
The circuit will return to normal mode if a valid LIN frame is received while entering the sleep mode (this valid frame can be addressed
to another slave).
15.2.5. Thermal Shutdown Mode
When thermal shutdown occurs, the circuit performs a SoftStop command and goes to Motor shutdown mode (see below).
15.2.6. Temperature Management
The AMIS-30623 monitors temperature by means of two thresholds and one shutdown level, as illustrated in the state diagram 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.
