... BU52004GUL, BU52014HFV ●Description The BU52004GUL and BU52014HFV are bipolar Hall ICs incorporating a polarity determination circuit that enables operation (output) on both the S- and N-poles, with the polarity judgment based on the output processing configuration. These Hall IC products can be in with movie, mobile phone and other applications involving crystal panels to detect the (front-back) location or determine the rotational direction of the panel. ● ...

... BU52004GUL, BU52014HFV ●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 important to take physical safety measures such as fusing when implementing any special mode that operates in excess of absolute rating limits ...
