● Description of Operations
Micropower Operation (Small current using intermittent action)
The dual output bipolar detection Hall IC adopts an
intermittent operation method to save energy. At startup, the
Hall elements, amp, comparator and other detection circuits
power ON and magnetic detection begins. During standby,
the detection circuits power OFF, thereby reducing current
consumption. The detection results are held while standby
is active, and then output.

Fig.21
The Hall elements form an equivalent Wheatstone (resistor)
bridge circuit. Offset voltage may be generated by a
differential in this bridge resistance, or can arise from
changes in resistance due to package or bonding stress. A
dynamic offset cancellation circuit is employed to cancel this
offset voltage.
When Hall elements are connected as shown in Fig. 21 and a
magnetic field is applied perpendicular to the Hall elements,
voltage is generated at the mid-point terminal of the bridge.
This is known as Hall voltage.
Dynamic cancellation switches the wiring (shown in the
figure) to redirect the current flow to a 90˚ angle from its
original path, and thereby cancels the Hall voltage.
The magnetic signal (only) is maintained in the sample/hold
circuit during the offset cancellation process and then
released.

The dual output Omnipolar detection Hall IC detects magnetic fields running perpendicular to the top surface of the package.
There is an inverse relationship between magnetic flux density and the distance separating the magnet and the Hall IC:
when distance increases magnetic density falls. When it drops below the operate point (Bop), output goes HIGH. When the
magnet gets closer to the IC and magnetic density rises, to the operate point, the output switches LOW. In LOW output
mode, the distance from the magnet to the IC increases again until the magnetic density falls to a point just below Bop, and
output returns HIGH. (This point, where magnetic flux density restores HIGH output, is known as the release point, Brp.)
This detection and adjustment mechanism is designed to prevent noise, oscillation and other erratic system operation.

The dual output Omnipolar detection Hall IC adopts an intermittent operation method in detecting the magnetic field during
startup, as shown in Fig. 25. It outputs to the appropriate terminal based on the detection result and maintains the output
condition during the standby period. The time from power ON until the end of the initial startup period is an indefinite interval,
but it cannot exceed the maximum period, 100ms. To accommodate the system design, the Hall IC output read should be
programmed within 100ms of power ON, but after the time allowed for the period ambient temperature and supply voltage.
●Magnet Selection
Of the two representative varieties of permanent magnet, neodymium generally offers greater magnetic power per volume
than ferrite, thereby enabling the highest degree of miniaturization, Thus, neodymium is best suited for small equipment
applications. Fig. 26 shows the relation between the size (volume) of a neodymium magnet and magnetic flux density. The
graph plots the correlation between the distance (L) from three versions of a 4mm X 4mm cross-section neodymium magnet
(1mm, 2mm, and 3mm thick) and magnetic flux density. Fig. 27 shows Hall IC detection distance – a good guide for
determining the proper size and detection distance of the magnet. Based on the BU52014HFV operating point max 5.0 mT,
the minimum detection distance for the 1mm, 2mm and 3mm magnets would be 7.6mm, 9.22mm, and 10.4mm, respectively.
To increase the magnet’s detection distance, either increase its thickness or sectional area.

Because they are configured for CMOS (inverter) output, the
output pins require no external resistance and allow direct
connection to the PC. This, in turn, enables reduction of the
current that would otherwise flow to the external resistor
during magnetic field detection, and supports overall low
current (micropower) operation.

●Operation Notes
1) Absolute maximum ratings
Exceeding the absolute maximum ratings for supply voltage, operating conditions, etc. may result in damage to or
destruction of the IC. Because the source (short mode or open mode) cannot be identified if the device is damaged in this
way, it is important to take physical safety measures such as fusing when implementing any special mode that operates in
excess of absolute rating limits.
2) GND voltage
Make sure that the GND terminal potential is maintained at the minimum in any operating state, and is always kept lower
than the potential of all other pins.
3) Thermal design
Use a thermal design that allows for sufficient margin in light of the power dissipation (Pd) in actual operating conditions.
4) Pin shorts and mounting errors
Use caution when positioning the IC for mounting on printed circuit boards. Mounting errors, such as improper positioning or
orientation, may damage or destroy the device. The IC may also be damaged or destroyed if output pins are shorted
together, or if shorts occur between the output pin and supply pin or GND.
5) Positioning components in proximity to the Hall IC and magnet
Positioning magnetic components in close proximity to the Hall IC or magnet may alter the magnetic field, and therefore the
magnetic detection operation. Thus, placing magnetic components near the Hall IC and magnet should be avoided in the
design if possible. However, where there is no alternative to employing such a design, be sure to thoroughly test and
evaluate performance with the magnetic component(s) in place to verify normal operation before implementing the design.

6) Slide-by position sensing
Fig.29 depicts the slide-by configuration employed for position sensing. Note that when the gap (d) between the magnet and
the Hall IC is narrowed, the reverse magnetic field generated by the magnet can cause the IC to malfunction. As seen in
Fig.30, the magnetic field runs in opposite directions at Point A and Point B. Since the dual output Omnipolar detection Hall
IC can detect the S-pole at Point A and the N-pole at Point B, it can wind up switching output ON as the magnet slides by in
the process of position detection. Fig. 31 plots magnetic flux density during the magnet slide-by. Although a reverse
magnetic field was generated in the process, the magnetic flux density decreased compared with the center of the magnet.
This demonstrates that slightly widening the gap (d) between the magnet and Hall IC reduces the reverse magnetic field
and prevents malfunctions.

7) Operation in strong electromagnetic fields
Exercise extreme caution about using the device in the presence of a strong electromagnetic field, as such use may cause
the IC to malfunction.
8) Common impedance
Make sure that the power supply and GND wiring limits common impedance to the extent possible by, for example,
employing short, thick supply and ground lines. Also, take measures to minimize ripple such as using an inductor or
capacitor.
9) GND wiring pattern
When both a small-signal GND and high-current GND are provided, single-point grounding at the reference point of the set
PCB is recommended, in order to separate the small-signal and high-current patterns, and to ensure that voltage changes
due to the wiring resistance and high current do not cause any voltage fluctuation in the small-signal GND. In the same way,
care must also be taken to avoid wiring pattern fluctuations in the GND wiring pattern of external components.
10) Exposure to strong light
Exposure to halogen lamps, UV and other strong light sources may cause the IC to malfunction. If the IC is subject to such
exposure, provide a shield or take other measures to protect it from the light. In testing, exposure to white LED and
fluorescent light sources was shown to have no significant effect on the IC.
11) Power source design
Since the IC performs intermittent operation, it has peak current when it’s ON. Please taking that into account and under
examine adequate evaluations when designing the power source.
