DESCRIPTION
The APS13290 and APS13291 are three-wire, planar Hall-effect
sensor integrated circuits (ICs) especially suited for operation
over extended temperature ranges (up to 125°C).
This family of precision Hall-effect latch ICs are ideal for
industrial and consumer applications and feature performance
enhancements permitting high-temperature operation up to
175°C junction temperatures. In addition, the APS13290/1
include a number of features designed specifically to maximize
system robustness, such as reverse-polarity protection, output
current limiter, overvoltage, and EMC protection.
The single silicon chip includes: a voltage regulator, a Hall
plate, small signal amplifier, chopper stabilization, Schmitt
trigger, and a short-circuit-protected open-drain output. A
south pole of sufficient strength turns the output on; a north
pole of sufficient strength is necessary to turn the output off.
The devices include on-board transient protection for all pins,
permitting operation directly from a vehicle battery or regulator
with supply voltages from 2.8 to 24 V.
Two package styles provide a choice of through-hole or surface
mounting. Package type LH is a modified 3-pin SOT23W
surface-mount package, while UA is a three-pin ultramini SIP
for through-hole mounting. Both packages are lead (Pb) free
and RoHS compliant, with 100% matte-tin-plated leadframes.

FUNCTIONAL DESCRIPTION
OPERATION
The output of these devices switches low (turns on) when a magnetic field perpendicular to the Hall element exceeds the operate
point threshold, BOP (see Figure 2). After turn-on, the output voltage is VOUT(SAT) . The output transistor is capable of continuously
sinking up to 30 mA. When the magnetic field is reduced below
the release point, BRP , the device output goes high (turns off)
to VOUTOFF. 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
external mechanical vibration and electrical noise.
POWER-ON BEHAVIOR
Device power-on occurs once tON has elapsed. During the
time prior to tON, and after VCC ≥ VCC(min), the output state is
VOUT(SAT) (Low). After tON has elapsed, the output will correspond with the applied magnetic field for B > BOP or B < BRP.
See Figure 3 for an example.
Powering-on the device in the hysteresis range (less than BOP and
higher than BRP) will give an output state of VOUT(SAT). The correct state is attained after the first excursion beyond BOP or BRP .
POS
Removal of the magnetic field will leave the device output
latched on if the last crossed switchpoint is BOP, or latched off if
the last crossed switch point is BRP.

APPLICATIONS
VPULL-UP
VSUPPLY
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 1: Typical Application
Circuit, a 0.1 µF capacitor is typical. In applications where maximum robustness is required, such as long-life industrial motors,
additional measures may be taken. In Figure 4: Enhanced Protection Circuit, a resistor in series with the VCC pin and a capacitor
on the VOUT pin enhance the EMC immunity of the device. It is
up to the user to fully qualify the Allegro sensor IC in their end
system to ensure they achieve their system requirements.

CHOPPER STABILIZATION
A limiting factor for switchpoint accuracy when using Hall-effect
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 Allegro technique, dynamic quadrature offset cancellation,
removes key sources of the output drift induced by temperature
and package stress. This offset reduction technique is based on a
signal modulation-demodulation process. Figure 6 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 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. 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 APS13290 and APS13291 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.

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 MicroSystems 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 a relatively
small component of RθJA. Ambient air temperature, TA, and air
motion are significant external factors, damped by overmolding.
The resulting power dissipation capability directly reflects upon
the ability of the device to withstand extreme operating conditions. The junction temperature mission profile specified in the
Absolute Maximum Ratings table designates a total operating life
capability based on qualification for the most extreme conditions,
where TJ may reach 175°C.
The silicon IC is heated internally when current is flowing into
the VCC terminal. When the output is on, current sinking into the
VOUT terminal generates additional heat. This may increase the
junction temperature, TJ, above the surrounding ambient temperature. The APS13290 and APS13291 are permitted to operate
up to TJ = 175°C. As mentioned above, an operating device will
increase TJ according to equations 1, 2, and 3 below. This allows
an estimation of the maximum ambient operating temperature.
For example, given common conditions such as: TA= 25°C,
VCC = 12 V, ICC = 2 mA, VOUT = 200 mV, IOUT = 20 mA (output
on), and RθJA = 165°C/W, then:
PD = (VCC × ICC) + (VOUT × IOUT) =
(12 V × 2 mA) + (200 mV × 20 mA) =
24 mW + 4 mW = 28 mW
ΔT = PD × RθJA = 28 mW × 165°C/W = 4.6°C
TJ = TA + ΔT = 25°C + 4.6°C = 29.6°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.
For example, given the conditions RθJA = 228°C/W, TJ(max) =
175°C, VCC(max) = 24 V, ICC(max) = 3.25 mA, VOUT = 500 mV,
and IOUT = 30 mA (output on), the maximum allowable operating
ambient temperature can be determined.
The power dissipation required for the output is shown below:
PD(VOUT) = VOUT × IOUT = 500 mV × 30 mA = 15 mW
The power dissipation required for the IC supply is shown below:
PD(VCC) = VCC × ICC = 24 V × 3.25 mA = 78 mW
Next, by inverting using equation 2:
ΔT = PD × RθJA = [PD(VOUT) + PD(VCC)] × 228°C/W =
(15 mW + 78 mW) × 228°C/W =
93 mW × 228°C/W = 21.2°C
Finally, by inverting equation 3 with respect to voltage:
TA(est) = TJ(max) – ΔT = 175°C – 21.2°C = 153.8°C
(1) In the above case, there is sufficient power dissipation capability
to operate up to TA(est). The example indicates that TA(max)
ΔT = PD × RθJA
(2) can be as high as 153.8°C without exceeding TJ(max). However,
the TA(max) rating of the devices is 125°C; the APS13290 and
TJ = TA + ΔT (3) APS13291
performance is not guaranteed above TA = 125°C.
