ST0–Gauge0—Junctionovertemperature.Alogic[1]onthis
bit indicates coil drive circuitry dedicated to drive Gauge 0 has
exceeded the maximum allowable junction temperature since
the last SPI communication. Additionally, the same indication
signals the circuitry Gauge 0 is disabled. It is recommended the
pointer be re-calibrated using the RTZ command after re-
enabling the gauge, using the PECR command. This bit
remains logic [1] until the gauge is re-enabled.
0 = Temperature within range
1 = Gauge 0 maximum allowable junction temperature
condition has been reached
DEVICE FUNCTIONAL DESCRIPTION
State Machine Operation
The two-phase stepper motor is defined as maximum
velocity and acceleration, and deceleration. It is the purpose of
the stepper motor state machine to drive the motor with
maximum performance while remaining within the motor’s
velocity and acceleration constraints.
When commanded, the motor should accelerate constantly
to its maximum velocity then decelerate and stop at the desired
position. During the deceleration phase, the motor should not
exceed the maximum deceleration. A required function of the
state
machine is to ensure the deceleration phase begins at the
correct time, or position.
During normal operation, both stepper motor rotors are
microsteppedwith24stepsper electricalrevolution. See Figure
6. A complete electrical revolution results in 2 degrees of
pointer movement. There is a second, and smaller state,
machine in the IC controlling these microsteps. This state
machine receives
clockwise
or
counter-clockwise
index
commands at intervals, stepping the motor in the appropriate
direction by adjusting the current in each coil. Normalized
values can be seen in Table 13.
