Introduction
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
- Ideally suited for wheel keys or trackballs
- Micropower operation (small current consumption via intermittent operation method)
- Ultra-small outline package
- Supports 1.8V supply voltage
- High ESD resistance: 8kV (HBM)
Applications
- Wheel keys (zero-contact selection dials)
- Trackballs
- Other interface applications
