Device Operation
Power-On
When power (VCC > VCC(min)) is applied to the
device, a short period of time is required to activate the various
portions of the IC. During this period, the ATS682 powers-on in
the high current state, ICC(HIGH). After power-on, there are condi-
tions that could induce a change in the output state. Such an event
could be caused by thermal transients, but it would also require a
static applied magnetic field, proper signal polarity, and particular
direction and magnitude of internal signal drift.
Initial Offset Adjust
The IC initially compensates for differ-
ential offset, ΔBAPP, that results from chip, magnet, and instal-
lation alignment. Once the effective differential magnetic offset
has been cancelled, the digital tracking DAC is ready to track the
signal and provide output switching.
The period of time required for both power-on and initial offset
adjust is defined as the Power-On Time specification.
Calibration Mode
The calibration mode allows the IC to auto-
matically select the proper signal gain and continue to adjust for
DC differential magnetic offset. The AGC is active, and selects
the optimal signal gain based on the amplitude of the VPROC
signal. Following each adjustment to the AGC DAC, the Offset
DAC is also adjusted to ensure the internal analog signal is prop-
erly centered. During this mode, the tracking DAC is active and
output switching occurs, but the duty cycle is not guaranteed to
be within specification.
Running Mode
After the initial calibration process (CALI
edges) establishes a signal gain, the device moves to Running
mode. During Running mode, the IC tracks the input signal and
continues to give an output edge for every peak of the signal.
AOA remains active to compensate for any offset drift over time.
The ATS682 also incorporates an algorithm for adjusting the
signal gain during Running mode. This algorithm is designed to
optimize the VPROC signal amplitude in instances where the mag-
netic signal during the calibration period is not representative of
the amplitude of the magnetic signal for the installed application
air gap (see figure 9).

Figure 9: Operation of Running Mode Gain Adjust.
Position 1. The device is initially powered-on. Self-calibration occurs.
Position 2. Small amplitude oscillation of the target sends an erroneously small differential signal to the device. The amplitude of VPROC is greater than
the switching hysteresis (BOP and BRP), and the device output switches.
Position 3. The calibration period completes on the third rising output edge, and the device enters Running mode.
Position 4. True target rotation occurs and the correct magnetic signal is generated for the installation air gap. The established signal gain is too large for
the rotational magnetic signal of the target, at the given air gap.
Position 5. Running mode calibration corrects the signal gain to an optimal level for the installation air gap.
