螴ntermittent Operation at Power ON
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The bipolar detection Hall IC adopts an intermittent operation method in detecting the magnetic field during startup, as
shown in Fig. 69. 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 dont adopts an intermittent operation method.
 
螹agnet 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 magnets detection distance, either increase its thickness or sectional area.
