DESCRIPTION
The ATS693LSG is an optimized Hall-effect integrated circuit
(IC) and rare earth pellet combination that provides a userfriendly solution for direction detection and true zero-speed,
digital gear tooth sensing. The small package can be easily
assembled and used in conjunction with a wide variety of gear
tooth sensing applications.
The IC employs patented algorithms for the special operational
requirements of automotive transmission applications. The
speed and direction of the target are communicated through a
variable pulse width output protocol. The ATS693 is particularly
adept at handling vibration without sacrificing maximum air
gap capability or creating any erroneous direction information.
Even higher angular vibration caused by engine cranking is
completely rejected by the device. The advanced vibration
detection algorithm systematically calibrates the sensor IC
on the initial teeth of true target rotation and not on vibration,
always guaranteeing an accurate signal in running mode.
Advanced signal processing and innovative algorithms make
the ATS693 an ideal solution for a wide range of speed and
direction sensing needs.
This device is available in a lead (Pb) free 4-pin SIP package
with a 100% matte tin plated leadframe.

7If the minimum signal phase separation is not maintained during or after a signal variation event, output may be blanked or non-direction pulses may occur. A signal variation event during power-on may increase the quantity of edges required to get correct direction pulses.
8Power-on frequency ≤ 200 Hz. Higher power-on frequencies may require more input magnetic cycles until directional output pulses are achieved.

Three-Wire, Differential, Vibration Resistant
Sensor IC with Speed and Direction Output
ATS693LSG
FUNCTIONAL DESCRIPTION
Sensing Technology
FORWARD ROTATION (SEE PANEL A IN FIGURE 3)
The sensor IC contains a single-chip Hall-effect circuit that
supports a trio of Hall elements. These elements are used in
differential pairs to provide electrical signals containing information regarding edge position and direction of target rotation. The
ATS693 is intended for use with ferromagnetic targets.
When the target is rotating such that a tooth near the sensor IC
passes from pin 4 to pin 1, this is referred to as forward rotation.
Forward rotation is indicated on the output by a tw(FWD) (45 μs
typical) pulse width.
After proper power is applied to the sensor IC, it is capable of
providing digital information that is representative of the magnetic features of a rotating target. The waveform diagrams in
figure 4 present the automatic translation of the target profiles,
through their induced magnetic profiles, to the digital output
signal of the sensor IC.
REVERSE ROTATION (SEE PANEL B IN FIGURE 3)
When the target is rotating such that a tooth passes from pin 1 to
pin 4, it is referred to as reverse rotation. Reverse rotation is indicated on the output by pulse widths of tw(REV) (90 μs (typical)).
Direction Detection
Target
The sensor IC compares the relative phase of its two differential
channels to determine in which direction the target is moving.
The relative switching order is used to determine the direction,
which is communicated through the output protocol.
Data Protocol Description
When a target passes in front of the device (opposite the branded
face of the package case), the ATS693 generates an output pulse
for each tooth of the target. Speed information is provided by the
output pulse rate, while direction of target rotation is provided by
the duration of the output pulses. The sensor IC can sense target
movement in both the forward and reverse directions.

TIMING
As shown in figure 5, the pulse appears at the output slightly
before the sensed magnetic edge traverses the package branded
face. For targets in forward rotation, this shift, Δfwd, results in
the pulse corresponding to the valley with the sensed mechanical
edge, and for targets in reverse rotation,
the shift, Forward
Δrev, results in
Target Rotation

sensed mechanical edge that
Valleystimulates

same for both forward and reverse rotation by using only one
channel to control
Targetoutput switching.

Sensor IC with Speed and Direction Output
ATS693LSG
Start-Up Detection / Calibration
When power is applied to the ATS693, the sensor IC internally detects the profile of the target. The gain and offset of
the detected signals are adjusted during the calibration period,
normalizing the internal signal amplitude for the air gap range of
the device.
The Automatic Gain Control (AGC) feature ensures that operational characteristics are isolated from the effects of installation
air gap variation.
Automatic Offset Adjustment (AOA) is circuitry that compensates for the effects of chip, magnet, and installation offsets.
This circuitry works with the AGC during calibration to adjust
VPROC in the internal A-to-D range to allow for acquisition of
signal peaks. AOA and AGC function separately on the two
differential signal channels.
Direction information is available after calibration is complete.
Figure 7 shows where the first output edges may occur for various starting target phases.

APPLICATION INFORMATION
Power Derating
The device must be operated below the maximum junction
temperature of the device, TJ(max). Under certain combinations of
peak conditions, reliable operation may require derating supplied
power or improving the heat dissipation properties of the application. This section presents a procedure for correlating factors
affecting operating TJ. (Thermal data is also available on the
Allegro website.)
The Package Thermal Resistance, RθJA, is a figure of merit summarizing the ability of the application and the device to dissipate
heat from the junction (die), through all paths to the ambient air.
Its primary component is the Effective Thermal Conductivity, K,
of the printed circuit board, including adjacent devices and traces.
Radiation from the die through the device case, RθJC, is relatively
small component of RθJA. Ambient air temperature, TA, and air
motion are significant external factors, damped by overmolding.
The effect of varying power levels (Power Dissipation, PD), can
be estimated. The following formulas represent the fundamental
relationships used to estimate TJ, at PD. PD = VIN × IIN (1)
ΔT = PD × RθJA (2)
TJ = TA + ΔT
(3)
For example, given common conditions such as: TA= 25°C,
VCC = 12 V, ICC = 6.5 mA, and RθJA = 126 °C/W, then:
Example: Reliability for VCC at TA = 150°C, package SG, using a
single-layer PCB.
Observe the worst-case ratings for the device, specifically: RθJA = 126 °C/W, TJ(max) = 165°C, VCC(max) = 24 V, and
ICC(max) = 12 mA.
Calculate the maximum allowable power level, PD(max). First,
invert equation 3:
ΔTmax = TJ(max) – TA = 165 °C – 150 °C = 15 °C
This provides the allowable increase to TJ resulting from internal
power dissipation. Then, invert equation 2:
PD(max) = ΔTmax ÷ RθJA = 15°C ÷ 126 °C/W = 119 mW
Finally, invert equation 1 with respect to voltage:
VCC(est) = PD(max) ÷ ICC(max) = 119 mW ÷ 12 mA = 9.9 V
The result indicates that, at TA, the application and device can
dissipate adequate amounts of heat at voltages ≤ VCC(est).
Compare VCC(est) to VCC(max). If VCC(est) ≤ VCC(max), then
reliable operation between VCC(est) and VCC(max) requires
enhanced RθJA. If VCC(est) ≥ VCC(max), then operation between
VCC(est) and VCC(max) is reliable under these conditions.

PD = VCC × ICC = 12 V × 6.5 mA = 78 mW
ΔT = PD × RθJA = 78 mW × 126 °C/W = 9.8°C

VCC
TJ = TA + ΔT = 25°C + 9.8°C = 34.8°C
A worst-case estimate, PD(max), represents the maximum allowable power level (VCC(max), ICC(max)), without exceeding
TJ(max), at a selected RθJA and TA.
