BU52040HFV Datasheet (ROHM) - Bipolar Latch Hall

BU52040HFV, Bipolar Latch Hall

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
