?SPAN class="pst BU52040HFV-TR_2601631_6">Description
BU52040 Hall Effect IC for wheel keys / trackballs is designed to detect a switch in magnetic field from N to S (or vice versa)
and maintain its detection result on the output until the next switch. Output is pulled low for S-pole fields and high for N-pole
fields. This IC is ideal for detecting the number of shaft rotations inside of a wheel key, trackball, or other similar applications.
Using two ICs can also enable detection of rotation direction.
?SPAN class="pst BU52040HFV-TR_2601631_6">Features
1) Ideally suited for wheel keys or trackballs
2) Micropower operation (small current consumption via intermittent operation method)
3) Ultra-small outline package
4) Supports 1.8 V supply voltage
5) High ESD resistance: 8kV (HBM)
?SPAN class="pst BU52040HFV-TR_2601631_6">Applications
Wheel keys (zero-contact selection dials), trackballs, and other interface applications.
