BU52040HFV Datasheet | ROHM

Hall IC Series Bipolar Latch Hall IC No.10045EBT05 - 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. - Features 1) Ideally suited for wheel keys or trackballs 2) Micropower operation (small current consumption via intermittent operation method) 3) Ultra-small outline...
