Datasheet - Application In form atio n

An equal output of all read out data is sufficient to verify the OTP programming. If the data output is a mismatch, then the programming of the

OTP was not successful and can cause a change of the OTP register content during operation over temperature and life time.

8.2.3 Physical Placement of the Magnet

The best linearity can be achieved by placing the center of the magnet exactly over the defined center of the chip as shown in Figure 26.

8.2.4 Magnet Placement

defined center of the IC.

The magnet may be placed below or above the device. The distance should be chosen such that the magnetic field on the die surface is within

the specified limits (see Figure 26). The typical distance “z” between the magnet and the package surface is 0.5mm to 1.5mm, provided the

recommended magnet material and dimensions (6mm x 3mm) are used. Larger distances are possible, as long as, the required magnetic field

strength stays within the defined limits.

However, a magnetic field outside the specified range may still produce usable results, but the out-of-range condition will be indicated by an

alarm forcing the output into the failure band.
