OH401 Hall Effect Unipolar IC

General Description

Part No：OH401  

Operate temperature：-40～125℃  

Package：1000pcs/bag

OH401 includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. While the magnetic flux density (B) is larger than threshold Bop, the OUT pin turns on (low). When B < Brp, the OUT pin go into “off ” state.
