Vertical and Planar Hall-Effect Switches
DESCRIPTION (continued)
The devices include on-board reverse-battery and overvoltage Two package styles provide a choice of through-hole or surface
protection for operating directly from an automobile battery, as mounting. Package type LH is a modified 3-pin SOT23W surface
well as protection from shorts to ground by limiting the output mount package, while package type UA is a 3-pin ultra-mini SIP
current until the short is removed. The device is especially suited for through-hole mounting. Both packages are lead (Pb) free, with
for operation from unregulated supplies.
100% matte-tin-plated leadframes.

Configurations xPL and xPH. The omnipolar operation of these
devices allows actuation with either a north or a south polarity
field. The xPL operates using the standard output polarity conven-
tion. Fields exceeding the operating points, BOPS or BOPN, will turn
the output on (low). When the magnetic field is removed or reduced
below the release point, BRPN or BRPS, the device output turns off
(goes high). The xPH is complementary, in that for the device, a
north or south polarity field exceeding the operate points, BOPS
or BOPN, will turn the output off (high). Removal of the field, or
reduction below the release point threshold, BRPS or BRPN, will turn
the output on (low). See Figure 3 for omnipolar switching behavior.
Operation
The APS11000 and APS11060 are integrated Hall-effect sensor
ICs with an open-drain output. Table 1 offers a guide for select-
ing the output polarity configuration, further explained in the
configuration sections below. The open-drain output is an NMOS
transistor that actuates in response to a magnetic field. The direc-
tion of the applied magnetic field is perpendicular to the branded
face for the APS11000, and parallel with the branded face for
the APS11060; see Figure 5 for an illustration. The devices are
offered in two packages: the UA package, a 3-pin through-hole
mounting configuration, or in the LH package, a 3-pin surface-
mount configuration. See the Selection Guide for a complete list
of available options.
After turn-on, the output transistor is capable of sinking current
up to the short circuit current limit, IOM, which is a minimum of
15 mA. The difference in the magnetic operate and release points
is the hysteresis, BHYS, of the device. This built-in hysteresis
allows clean switching of the output even in the presence of exter-
nal mechanical vibration and electrical noise.
Configurations xSL and xSH. The unipolar output of these
devices is actuated when a south-polarity magnetic field perpen-
dicular to the Hall element exceeds the operate point threshold,
BOPS. When BOPS is exceeded, the xSL output turns on (goes
low). The xSH is complementary, in that for this device the output
turns off (goes high) when BOPS is exceeded. When the magnetic
field is removed or reduced below the release point, BRPS, the
device outputs return to their original state—off for the xSL and
on for the xSH. See Figure 3 for unipolar south switching behav-
ior.
Configurations xNL and xNH. The unipolar output of these
devices is actuated when a north-polarity magnetic field perpen-
dicular to the Hall element exceeds the operate point threshold,
BOPN. When BOPN is exceeded, the xNL output turns on (goes low).
The xNH is complementary, in that for this device the output turns
off (goes high) when BOPN is exceeded. When the magnetic field
is removed or reduced below the release point, BRPN, the device
outputs return to their original state—off for the xNL and on for the
xNH. See Figure 3 for unipolar north switching behavior.

Applications
It is strongly recommended that an external bypass capacitor be
connected (in close proximity to the Hall element) between the
supply and ground of the device to guarantee correct performance
under harsh environmental conditions and to reduce noise from
internal circuitry. As is shown in Figure 6: Typical and Enhanced
Protection Application Circuits, a 0.1 µF capacitor is required.
Extensive applications information for Hall-effect devices is
available in:
• Hall-Effect IC Applications Guide, AN27701,
• Hall-Effect Devices: Guidelines for Designing Subassemblies
Using Hall-Effect Devices AN27703.1
• Soldering Methods for Allegro’s Products – SMD and Through-
Hole, AN26009
In applications where the APS11000 or APS11060 receives
its power from an unregulated source such as a car battery, or
where greater immunity is required, additional measures may
be employed. Specifications for such transients will vary, so
protection circuit design should be optimized for each application.
For example, the circuit shown in Figure 6 includes an optional
series resistor and output capacitor which improves performance
during Powered ESD testing (ISO 10605) and Bulk Current
Injection testing (ISO 11452-4).

CHOPPER STABILIZATION
A limiting factor for switchpoint accuracy when using Hall-effect offset causing the magnetically induced signal to recover its
original spectrum at baseband while the DC offset becomes a
high-frequency signal. Then, using a low-pass filter, the signal
passes while the modulated DC offset is suppressed. Allegro’s
innovative chopper-stabilization technique uses a high-frequency
clock.
technology is the small signal voltage developed across the Hall
plate. This voltage is proportionally small relative to the offset
that can be produced at the output of the Hall sensor. This makes
it difficult to process the signal and maintain an accurate, reliable
output over the specified temperature and voltage range. Chopper
stabilization is a proven approach used to minimize Hall offset.
The high-frequency operation allows a greater sampling rate
that produces higher accuracy, reduced jitter, and faster signal
processing. Additionally, filtering is more effective and results
in a lower noise analog signal at the sensor output. Devices such
as the APS11000 and APS11060 that use this approach have an
extremely stable quiescent Hall output voltage, are immune to
thermal stress, and have precise recoverability after temperature
cycling. This technique is made possible through the use of a
BiCMOS process which allows the use of low offset and low
noise amplifiers in combination with high-density logic and
sample-and-hold circuits.
The technique, dynamic quadrature offset cancellation, removes
key sources of the output drift induced by temperature and pack-
age stress. This offset reduction technique is based on a signal
modulation-demodulation process. Figure 7: Model of Chopper
Stabilization Circuit (Dynamic Offset Cancellation) illustrates
how it is implemented.
The undesired offset signal is separated from the magnetically
induced signal in the frequency domain through modulation. The
subsequent demodulation acts as a modulation process for the

POWER DERATING
The device must be operated below the maximum junction tem-
perature, TJ(max). Reliable operation may require derating supplied
power and/or improving the heat dissipation properties of the
application.
This provides the allowable increase to TJ resulting from internal
power dissipation. Then, using equation 2 first for the output as
shown below:
PD(VOUT) = VOUT × IOUT = 500 mV × 20 mA = 10 mW
Then, for the VCC supply:
Thermal Resistance, RθJA (junction to ambient), 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 ambient
air. RθJA is dominated by the Effective Thermal Conductivity,
K, of the printed circuit board which includes adjacent devices
and board layout. Thermal resistance from the die junction to
case, RθJC, is a relatively small component of RθJA. Ambient air
temperature, TA, and air motion are significant external factors in
determining a reliable thermal operating point.
PD(VCC) = VCC × ICC = 24 V × 5 mA = 120 mW
Combine the power dissipated by the device pins:
PD(total) = (PD(VOUT) + PD(VCC)
)
PD(total) = (10 mW + 120 mW) = 130 mW
Next, solve for the maximum allowable VCC for the given condi-
tions using equation 1:
VCC(est) = PD(total) ÷ (ICC + IOUT
130 mW ÷ (5 mA + 20 mA)
)
The following three equations can be used to determine operation
points for given power and thermal conditions:
VCC(est) =130 mW ÷ 25 mA = 5.2 V
PD = VIN × IIN (1)
ΔT = PD × RθJA (2)
TJ = TA + ΔT (3)
The result indicates that, at TA, the application and device can dis-
sipate adequate amounts of heat at voltages ≤ VCC(est)
.
If the application requires VCC > VCC(est) then RθJA must by
improved. This can be accomplished by adjusting the layout, PCB
materials, or by controlling the ambient temperature.
Determining Junction Temperature
For example, given common conditions: TA = 25°C, VCC = 12 V,
Determining Maximum TA
ICC = 2.5 mA, VOUT(SAT) = 100 mV, IOUT = 5 mA, and RθJA
165°C/W, then:
=
In cases where the VCC(max) level is known, and the system
designer would like to determine the maximum allowable ambient
temperature, TA(max), the calculations can be reversed.
PD = (VCC × ICC) + (VOUT × IOUT) =
(12 V × 2.5 mA) + (100 mV × 5 mA) =
30 mW + 0.5 mW = 30.5 mW
For example, in a worst-case scenario with conditions VCC(max)
=
24 V, ICC(max) = 5 mA, VOUT = 500 mV, IOUT(max) = 15 mA, and
RθJA = 228°C/W, for the LH package using equation 1, the largest
possible amount of dissipated power is:
ΔT = PD × RθJA = 30.5 mW × 165°C/W = 5°C
TJ = TA + ΔT = 25°C + 5°C = 30°C
PD = VIN × IIN
PD = PD(VOUT) + PD(VCC) = 500 mV × 15 mA + 24 V × 5 mA
PD = 7.5 mW + 120 mW = 127.5 mW
Then, by rearranging equation 3:
Determining Maximum VCC
For a given ambient temperature (TA), the maximum allowable
power dissipation as a function of VCC can be calculated. PD(max)
represents the maximum allowable power level without exceeding
TJ(max), at a selected RθJA and TA.
,
TA(max) = TJ(max) – ΔT
Example: VCC estimation using the conditions RθJA = 228°C/W,
TA(max) = 165°C – (127.5 mW × 228°C/W)
TA(max) = 165°C – 29.1°C = 135.9°C
TA(max) = 150°C, TJ(max) = 165°C, VCC(max) = 24 V, ICC(max)
=
5 mA, VOUT = 500 mV, and IOUT = 20 mA (output on), calculate
the maximum allowable power level, PD(max), first using equa-
tion 3:
Finally, note that the TA(max) rating of the device is 150°C and
performance is not guaranteed above this temperature for any
power level.
ΔT(max) = TJ(max) – TA = 165°C – 150°C = 15°C
