9.2.2 Main Control and Register, OTP Memory + RAM
9.2.2.1 Power-up Phase
Power-up phase of the AMIS-30622 will not exceed 10ms.
After this phase, the AMIS-30622 is in Shutdown mode,
ready to receive I
2
C messages and to execute the
associated commands. After power-up, the registers and
flags are in the Reset state, some of them being loaded
with the OTP memory content (see § 9.2.2.13 OTP Memory
Structure)
9.2.2.2 Reset State
After power-up, or after a reset occurrence (e.g. a micro cut
on pin VBB has made Vdd to go below VddReset level), the
H-bridges will be in high impedance mode and the registers
and flags will be in a predetermined position. See also §
9.2.2.7 Motor Shutdown Mode and Digital Supply Reset in
§ 9.2.2.9 Flags Table.
9.2.2.3 Soft Stop
A Soft Stop is an immediate interruption of a motion, but
with a deceleration phase. At the end of this action, the
register
TagPos
is loaded with the value contained in
register
ActPos
to avoid an attempt of the circuit to
achieve the motion (see § 9.2.2.9 Flags Table).
The circuit is then ready to execute a new positioning
command, provided thermal and electrical conditions allow
for it.
9.2.2.4 Thermal Shutdown Mode
When thermal shutdown occurs, the circuit performs a
SoftStop
command and goes to motor shutdown mode
(see below).
9.2.2.5 Temperature Management
The AMIS-30622 monitors temperature by mean 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
GetFullStatus1
command.
