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. Period Startup time Standby time Reference period: 50ms (MAX100ms) Reference startup time: 48s t Fig.65 (Offset Cancelation) VDD I Bx + Hall Voltage BD7411G don't adopts an intermittent operation method. 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. 66 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. GND Fig.66 www.rohm.com (c) 2011 ROHM Co., Ltd.

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. www.rohm.com (c) 2011 ROHM Co., Ltd.

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. BD7411G don't adopts an intermittent operation method. 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. 70 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. 71 shows Hall IC detection distance - a good guide for determining the proper size and detection distance of the magnet. Based on the BU52011HFV, BU52015GUL 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. 10 Magnetic flux density [mT] 9 t=3mm 8 t=1mm 7 t=2mm 6 5 4 3 2 7.6mm 1 9.2mm 10.4mm 0 0 2 4 6 8 10 12 14 Magnet Hall IC distance L [mm] 16 18 20 Fig.70 X Magnet t Y X=Y=4mm t=1mm,2mm,3mm Magnet size t Magnet material: NMX-44CH Maker: Hitachi Metals.,LTD L: Variable ...Flux density measuring point Fig.71 Magnet Dimensions and Flux Density Measuring Point www.rohm.com (c) 2011 ROHM Co., Ltd.

GND Fig.72 www.rohm.com (c) 2011 ROHM Co., Ltd. All rights reserved. 27/31 2011.12 - Rev.G BU52001GUL,BU52011HFV,BU52021HFV,BU52015GUL,BU52025G,BU52053NVX, BU52054GWZ,BU52055GWZ,BU52056NVX,BU52061NVX,BD7411G Technical Note Notes for use 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. Magnet Slide Hall IC L Magnetic Flux A S N Fig.73 B Magnetic Flux Magnetic fux density[mT] 6) Slide-by position sensing Fig.73 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.74, the magnetic field runs in opposite directions at Point A and Point B. Since the bipolar 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. 75 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. 10 8 6 4 2 0 -2 -4 -6 -8 -10 Reverse Magnetic Field 0 1 2 3 4 5 6 7 8 9 Fig.74 Fig.75 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. www.rohm.com (c) 2011 ROHM Co., Ltd.
