BU52040HFV - Bipolar Latch Hall

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.

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).

Hall IC Series Bipolar Latch Hall IC BU52040HFV 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 package 4) Supports 1.
