BU52040HFV hall equivalent, bipolar latch hall.
1) Ideally suited for wheel keys or trackballs 2) Micropower operation (small current consumption via intermittent operation method) 3) Ultra-small outline package 4) Sup.
Using two ICs can also enable detection of rotation direction.
*Features 1) Ideally suited for wheel keys or track.
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.
